The molecular structure is based on structures generated from information available in ECHA’s databases. Folic acid deficiency complications like tired blood anemia or incapacity of bowels in absorbing nutrients are also treated with folic acid supplementation. Food standards: amendment of standards of identity for enriched grain products to require addition of folic acid. For folate, 100% RI was set at 200 μg in 2011.[109]. [3] Manufactured folic acid, which is converted into folate by the body, is used as a dietary supplement and in food fortification as it is more stable during processing and storage. Folate derivatives participate in the biosynthesis of both purines and pyrimidines. [131][132], In 2017, it was the 96th most commonly prescribed medication in the United States, with more than eight million prescriptions. The structure of folic acid is shown in Figure 7. This leads to megaloblastic anemia, which is characterized by large, immature red blood cells. [66][67] Supplementing the diet with folic acid and vitamin B12 lowers plasma homocysteine. Molecular structure. The crystal and molecular structure of folic acid dihydrate has been determined by x-ray diffraction. 21 CFR Parts 136, 137, and 139", 10.1002/(SICI)1096-8628(19980724)78:4<381::AID-AJMG16>3.0.CO;2-E, "FDA muffed chance to reduce birth defects", "Folic acid intake from fortification in United States exceeds predictions", "Effect of food fortification on folic acid intake in the United States", "TABLE 1: Nutrient Intakes from Food and Beverages", "Updated Estimates of Neural Tube Defects Prevented by Mandatory Folic Acid Fortification — United States, 1995–2011", "Birth Defects COUNT | Folic Acid | NCBDDD | CDC", Formylation, hydroxymethylation and methylation using folate, Anatomical Therapeutic Chemical classification, Ergocalciferol and Cholecalciferol (Vitamin D), https://en.wikipedia.org/w/index.php?title=Folate&oldid=1002493824, World Health Organization essential medicines, Wikipedia articles needing page number citations from May 2013, Short description is different from Wikidata, Chemical articles with unknown parameter in Infobox drug, Infobox drug articles with non-default infobox title, Chemical articles with multiple CAS registry numbers, Articles containing unverified chemical infoboxes, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 January 2021, at 18:33. [1][28] The European Food Safety Authority (EFSA) refers to the collective set of information as Dietary Reference Values, with Population Reference Intake (PRI) instead of RDA, and Average Requirement instead of EAR. [6][49][50], Early after fortification programs were implemented, high intakes were theorized to accelerate the growth of preneoplastic lesions that could lead to cancer, specifically colon cancer. [56] Supplementation with folic acid at 1,000 to 2,500 μg/day – the amounts used in many of the supplement trials[13][56] – would result in higher concentrations of serum folate than what is achieved from diets high in food-derived folate. Because of the difference in bioavailability between supplemented folic acid and the different forms of folate found in food, the dietary folate equivalent (DFE) system was established. [82] A second enzyme, methylenetetrahydrofolate dehydrogenase (MTHFD2)[85] oxidizes 5,10-methylenetetrahydrofolate to an iminium cation which in turn is hydrolyzed to produce 5-formyl-THF and 10-formyl-THF. As a natural water -soluble substance, folic acid is involved in carbon transfer reactions of amino acid metabolism, in addition to purine and pyrimidine synthesis, and is essential for hematopoiesis and red blood cell production. [1] Folate deficiency in children may develop within a month of poor dietary intake. Final Rule. Its chemical structure contains three distinct parts, consisting of glutamic acid, a para-aminobenzoic acid (PABA) residue and a pteridine nucleus (Illus. Evidence of a negative health effect of folic acid in blood is not consistent, and folic acid has no known cofactor function that would increase the likelihood of a causal role for free FA in disease development. Wills demonstrated that anemia could be reversed with brewer's yeast. [36], Australia and New Zealand jointly agreed to wheat flour fortification through the Food Standards Australia New Zealand in 2007. CopyCopied, OVBPIULPVIDEAO-LBPRGKRZSA-N [3] Folic acid is also used as a supplement by women during pregnancy to reduce the risk of neural tube defects (NTDs) in the baby. Folic acid is a type of B vitamin that is normally found in foods such as dried beans, peas, lentils, oranges, whole-wheat products, liver, asparagus, beets, broccoli, brussels sprouts, and spinach. Three different oxidation states of carbon can bind to THF. [51] However, at blood concentrations achieved via food fortification, folic acid has no known cofactor function that would increase the likelihood of a causal role for free FA in disease development. [1], Folate in the form of folic acid is used to treat anemia caused by folate deficiency. [38], Folic acid is added to grain products in more than 80 countries, either as required or voluntary fortification,[11][36] and these fortified products make up a significant source of the population's folate intake. Folic acid is one of the B-complex vitamins required in order to produce red blood cells. They are derivatives of folic acid (see figure), which is also denominated pteroyl glutamic acid. [53] For prostate cancer risk, comparing low to high dietary folate showed no effect,[54][55] but the same two studies reported a significant increased risk for prostate cancer correlating to elevated serum folate. [113] Fortification is controversial, with issues having been raised concerning individual liberty,[104] as well as the theorized health concerns described in the Safety section. [1], The U.S. Institute of Medicine defines Estimated Average Requirements (EARs), Recommended Dietary Allowances (RDAs), Adequate Intakes (AIs), and Tolerable upper intake levels (ULs) – collectively referred to as Dietary Reference Intakes (DRIs). Folic acid is synthesized by bacteria from the substrate, para-amino-benzoic acid (PABA), and all cells require folic acid for growth. [101], Reviews of clinical trials that called for long-term consumption of folic acid in amounts exceeding the UL have raised concerns. Lizenz . Some cereals contain 100% of the daily value of folic acid a woman should take per day. 1 μg of folic acid supplement counts as 1.7 μg DFE. Overview; Side Effects; FAQ; Professional; Interactions; Reviews; More; Uses of Folic Acid, Vitamin B6, Vitamin B12, Omega-3 Acids, and … These are the pteridine ring, para-amino benzoic acid, and glutamic acid. Glycine, histidine, and sarcosine can also directly contribute to the THF-bound 1C pool. These cells replacement activity is very important as they must continuously form the DNA as part of their genetic structure. It was first isolated via extraction from spinach leaves by Herschel K. Mitchell, Esmond E. Snell, and Roger J… [39] Prenatal supplementation with folic acid did not appear to reduce the risk of preterm births. In dog breeds at risk for cleft lip and cleft palate dietary folic acid supplementation significantly decreased incidence. Hence folic acid must first be reduced to THF. Chemical structure of folic acid (vitamin B 9). [97] Thus, a deficiency in B12 can cause accumulation of methyl-THF, mimicking folate deficiency. In the late 1930s, folate was identified as the corrective substance in brewer's yeast. The Association of Bakers and the Green Party had opposed mandatory fortification, describing it as "mass medication. See biotin above). Vitamin B9 is represented by the group of folate, whose structure is derived from folic acid. [42] There was no relation between maternal folic acid supplementation and an increased risk for childhood asthma. [64][65] The supplement of folinic acid in people undergoing methotrexate treatment is to give less rapidly dividing cells enough folate to maintain normal cell functions. [120], While the Food Standards Agency recommended folic acid fortification,[121][122][123] and wheat flour is fortified with iron,[124] folic acid fortification of wheat flour is allowed voluntarily rather than required. [103], The U.S. National Center for Health Statistics conducts the biannual National Health and Nutrition Examination Survey (NHANES) to assess the health and nutritional status of adults and children in the United States. März 2007: Quelle: Self-made in BKChem + perl + vim. PRI for pregnancy is 600 μg/day, for lactation 500 μg/day. [82] This series of reactions using the β-carbon atom of serine as the carbon source provide the largest part of the one-carbon units available to the cell. [23] Within the field of nutrition, the "folates" are a family of essential nutrients related to folic acid obtained from natural sources whereas the term "folic acid" is reserved for the manufactured form that is used as a dietary supplement. [81], All of the biological functions of folic acid are performed by THF and its methylated derivatives. The most commonly mandatory fortified vitamin – in 62 countries – is folate; the most commonly fortified food is wheat flour. This reaction also consumes serine and pyridoxal phosphate (PLP; vitamin B6) and produces glycine and pyridoxal. [51][52] Subsequent meta-analyses of the effects of low versus high dietary folate, elevated serum folate, and supplemental folate in the form of folic acid have reported at times conflicting results. [28] In general, ULs are set for vitamins and minerals when evidence is sufficient. [76][77][78], Some studies show iron–folic acid supplementation in children under five may result in increased mortality due to malaria; this has prompted the World Health Organization to alter their iron–folic acid supplementation policies for children in malaria-prone areas, such as India. [14] In adults, normal total body folate is between 10 and 30 mg with blood levels of greater than 7 nmol/L (3 ng/mL). … These values differ somewhat from the U.S. [126] There were concerns expressed that the amount of folate added was insufficient. People with megaloblastic anemia need to be tested for vitamin B12 deficiency before treatment with folic acid, because if the person has vitamin B12 deficiency, folic acid supplementation can remove the anemia, but can also worsen neurologic problems. [52] The results of folic acid fortification on the rate of neural tube defects in Canada have been positive, showing a 46% reduction in prevalence of NTDs; the magnitude of reduction was proportional to the prefortification rate of NTDs, essentially removing geographical variations in rates of NTDs seen in Canada before fortification. Urheber: User:Mysid: Lizenz. [119] Folic acid food fortification became mandatory in 1998, with the fortification of 150 µg of folic acid per 100 grams of enriched flour and uncooked cereal grains. Folate deficiency can be caused by unhealthy diets that do not include enough vegetables and other folate-rich foods; diseases in which folates are not well absorbed in the digestive system (such as Crohn's disease or celiac disease); some genetic disorders that affect levels of folate; and certain medicines (such as phenytoin, sulfasalazine, or trimethoprim-sulfamethoxazole). [16] The term "folic" is from the Latin word folium (which means leaf) because it was found in dark-green leafy vegetables. Folic acid is a manufactured form of folate; folate can be found naturally in certain foods, such as leafy green vegetables, nuts, beans, and grains. The latter is a purely artificial compound and usually does not appear as metabolite. [7][104] After the discovery of the link between insufficient folic acid and neural tube defects, governments and health organizations worldwide made recommendations concerning folic acid supplementation for women intending to become pregnant. [94] These reactions are collectively known as folate-mediated one-carbon metabolism.[8][95]. A pterin (2-amino-4-hydroxy-pteridine) heterocyclic ring is linked by a methylene bridge to a p-aminobenzoyl group that in turn is bonded through an amide linkage to either glutamic acid or poly-glutamate. This treatment is very successful in replenishing tissues, even if deficiency was caused by malabsorption. A meta-analysis of global birth prevalence of spina bifida showed that when mandatory fortification was compared to countries with voluntary fortification or no fortification program, there was a 30% reduction in live births with spina bifida,[37] with some countries reporting a greater than 50% reduction. Methyl-THF converts vitamin B12 to methyl-B12 (methylcobalamin). Datum: 10. AI and UL are defined the same as in United States. Even so, fewer than half of pregnant women are exceeding the pregnancy RDA of 600 μg/day. [19], A meta-analysis of folate supplementation during pregnancy reported a 28% lower relative risk of newborn congenital heart defects. [98] The United Kingdom's Dietary Reference Value for folate, set by the Committee on Medical Aspects of Food and Nutrition Policy in 1991, is 200 μg/day for adults. The study conducted by Butterworth et al. 12-1). [13] There are concerns that large amounts of supplemental folic acid can hide vitamin B12 deficiency. As of December 21, 2018, 81 countries required food fortification with one or more vitamins. [67] However, several reviews reported that supplementation with folic acid alone or in combination with other B vitamins did not prevent development of cognitive impairment nor slow cognitive decline. Folic acid fortification is a process where synthetic folic acid is added to wheat flour or other foods with the intention of promoting public health through increasing blood folate levels in the populace. [28] Other symptoms include fatigue, gray hair, mouth sores, poor growth, and swollen tongue. [28] Folate deficiency is treated with supplemental oral folic acid of 400 to 1000 μg per day. [129] Much of the elder population take supplements that add 400 µg to their daily folic acid intake. August 2012: Quelle: Eigenes Werk: Urheber: Ayacop: SVG‑Erstellung Der Quelltext dieser SVG-Datei ist Diese Strukturformel wurde mit Inkscape erstellt. The active coenzyme form is tetrahydrofolate (THF). [73][74] The exact mechanisms involved in the development of schizophrenia and depression are not entirely clear, but the bioactive folate, methyltetrahydrofolate (5-MTHF), a direct target of methyl donors such as S-adenosyl methionine (SAMe), recycles the inactive dihydrobiopterin (BH2) into tetrahydrobiopterin (BH4), the necessary cofactor in various steps of monoamine synthesis, including that of dopamine. For children ages 1–17 years the PRIs increase with age from 120 to 270 μg/day. Glutamic acid is an amino acid that the body can actually synthesize by itself and is found in proteins. RDAs. Due to their close resemblance, folic acid and folate are widely considered to b… [1] This may result in a type of anemia in which red blood cells become abnormally large. Liver and liver products also contain high amounts of folate, as does baker's yeast. This means that fortification led to a bigger increase in folic acid intake than first projected, and that more than half the adults are consuming more than the RDA of 400 μg (as DFEs). [6][18][19][20] Historic names included L. ⁠casei, factor vitamin Bc and vitamin M.[2], The terms "folate" and "folic acid" have somewhat different meanings in different contexts, although sometimes used interchangeably. Excessive amounts derived from supplements are more of a concern than that derived from natural food sources and the relative proportion to vitamin B12 may be a significant factor in adverse effects. Folate is reduced to THF by the action of tetrahydrofolate reductase. [36], Veterinarians may test cats and dogs if a risk of folate deficiency is indicated. Folic Acid Tablets, USP 1 mg contain the following inactive ingredients: lactose monohydrate, microcrystalline cellulose, sodium starch glycolate and stearic acid. [29], Since folate deficiency limits cell division, erythropoiesis (production of red blood cells) is hindered. Folic acid helps your body produce and maintain new cells, and also helps prevent changes to DNA that may lead to cancer. [38] The United States Preventive Services Task Force recommends folic acid as the supplement or fortification ingredient, as forms of folate other than folic acid have not been studied. "[115][116] Food Safety Minister Kate Wilkinson reviewed the decision to fortify in July 2009, citing as reasons to oppose claims for links between over consumption of folate with increased risk of cancer. Folate is especially important during periods of frequent cell division and growth, such as infancy and pregnancy. [34] NTDs occur early in pregnancy (first month), therefore women must have abundant folate upon conception and for this reason there is a recommendation that any woman planning to become pregnant consume a folate-containing dietary supplement before and during pregnancy. [36] The most commonly fortified vitamin – as used in 62 countries – is folate; the most commonly fortified food is wheat flour, followed by maize flour and rice. There is evidence that folate consumption is protective. Folate deficiency hinders DNA synthesis and cell division, affecting hematopoietic cells and neoplasms the most because of their greater frequency of cell division. [26] Folate deficiency is diagnosed by analyzing a complete blood count (CBC) and plasma vitamin B12 and folate levels. Folic Acid Structural Formula. In 1931, researcher Lucy Wills made a key observation that led to the identification of folate as the nutrient required to prevent anemia during pregnancy. [56] A third supplementation meta-analysis limited to reporting only on colorectal cancer incidence showed that folic acid treatment was not associated with colorectal cancer risk.[57]. The vitamers of the folate group display a high variety of different structures. IPR-MUS LD50 85 mg kg-1, IVN-GPG LD50 120 mg kg-1, IVN-MUS LD50 239 mg kg-1, IVN-RAT LD50 500 mg kg-1, IVN-RBT LD50 410 mg kg-1, Organic Compound; Amine; Amide; Ester; Drug; Hematinic; Vitamin B Complex; Food Toxin; Dietary Supplement; Micronutrient; Metabolite; Nutraceutical; Household Toxin; Fungal Toxin; Natural Compound; Supplement, CAUTION: May irritate eyes, skin, and respiratory tract. Some breakfast cereals (ready-to-eat and others) are fortified with 25% to 100% of the recommended dietary allowance (RDA) for folic acid. [3][10] Low levels in early pregnancy are believed to be the cause of more than half of babies born with NTDs. Folate, also known as vitamin B9 and folacin,[6] is one of the B vitamins. Folic acid (as a vitamin in food) diffuses or is transported into mammalian cells. [11] Long-term supplementation with relatively large amounts of folic acid is associated with small reduction in the risk of stroke[12] and an increased risk of prostate cancer. [22][20] Within the field of biochemistry, folates refer to a class of biologically active compounds related to and including folic acid. Folate is the common form of vitamin B9 present in many whole foods, including leafy greens, beans, eggs, citrus fruit, avocados, and beef liver. Chemsrc provides Folic Acid(CAS#:59-30-3) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. In manchen Staaten könnte dies rechtlich nicht möglich sein. [117] In 2012 the delayed mandatory fortification program was revoked and replaced by a voluntary program, with the hope of achieving a 50% bread fortification target. Bone marrow depression (inducing leukopenia and thrombocytopenia) and acute kidney and liver failure have been reported. An N-acyl-amino acid that is a form of the water-soluble vitamin B9. [135] In 1931, researcher Lucy Wills made a key observation that led to the identification of folate as the nutrient required to prevent anemia during pregnancy. A meta-analysis of global birth prevalence of spina bifida showed that when mandatory fortification was compared to countries with voluntary fortification or no fortification program, there was a 30% reduction in live births with spina bifida. Voluntary nutrients may be shown if present in significant amounts. Folic Acid (B9) - Structure coenzyme DHFA NADPH DHFA reductase pteridine ring PABA Other "conjugates" exist that have more than one glutamic acid; these have reduced vitamin activity. Countries have implemented either mandatory or voluntary food fortification of wheat flour and other grains,[36] or else have no such program and depend on public health and healthcare practitioner advice to women of childbearing age. CopyCopied, CSID:5815, http://www.chemspider.com/Chemical-Structure.5815.html (accessed 13:07, Jan 25, 2021) In the 1920s, scientists believed folate deficiency and anemia were the same condition. [12] Two other meta-analyses reported a similar decrease in relative risk. For U.S. food and dietary supplement labeling purposes the amount in a serving is expressed as a percent of Daily Value (%DV). [118], Canadian public health efforts focused on promoting awareness of the importance of folic acid supplementation for all women of childbearing age and decreasing socio-economic inequalities by providing practical folic acid support to vulnerable groups of women. It’s also used in other conditions associated with folic acid deficiency like liver disease, ulcerative colitis, kidney dialysis and alcoholism. Folate is important for cells and tissues that divide rapidly. [43], Folate contributes to spermatogenesis. The chemistry symbols of this structural formula are drawn using the path text method. [75], A complex interaction occurs between folic acid, vitamin B12, and iron. [127], The fortification program was expected to raise a person's folic acid intake level by 70–130 µg/day;[128] however, an increase of almost double that amount was actually observed. [8][80], Animals, including humans, cannot synthesize folate and therefore must obtain folate from their diet. Instead of Daily Values, amounts are shown as percent of Reference Intakes (RIs). View information & documentation regarding Folic acid, including CAS, MSDS & more. The solution structure of folic acid was determined by the combined use of NMR experimental results, mechanics and dynamics calculations, and theoretical simulation of NMR spectra. [135] In the late 1990s, the U.S. and Canadian governments decided that despite public education programs and the availability of folic acid supplements, there was still a challenge for women of child-bearing age to meet the daily folate recommendations, which is when those two countries implemented folate fortification programs. Folic acid is in an extended conformation with the pteridine ring in the keto form. [58] Cancer cells divide rapidly, and drugs that interfere with folate metabolism are used to treat cancer. An erythrocyte folate level of 140 μg/L or lower indicates inadequate folate status. [6][1] The recommended adult daily intake of folate in the U.S. is 400 micrograms from foods or dietary supplements. [17], "Folate" (vitamin B9) refers to the many forms of folic acid and its related compounds, including tetrahydrofolic acid (the active form), methyltetrahydrofolate (the primary form found in blood), methenyltetrahydrofolate, folinic acid, folacin, and pteroylglutamic acid. folic acid. Because the neural tube closes in the first four weeks of gestation, often before many women even know they are pregnant, many countries in time decided to implement mandatory food fortification programs. Comparing low to high dietary folate showed a modest but statistically significant reduced risk of colon cancer. ChEBI Name folic acid: ChEBI ID CHEBI:27470: Definition An N-acyl-amino acid that is a form of the water-soluble vitamin B 9.Its biologically active forms (tetrahydrofolate and others) are essential for nucleotide biosynthesis and homocysteine remethylation. On the other hand, folic acid is a synthesized version of vitamin B9 that is added to processed foods and the common version used in supplements. Cats with exocrine pancreatic insufficiency, moreso than dogs, may have low serum folate. Folic acid colour ranges from yellow to orange and is a tasteless needle-like crystal. [12][47] The effect was also larger for the studies that were conducted in countries that did not have mandatory grain folic acid fortification. Folic acid has a molecular structure that is nearly identical to folate. [47][48], Chronically insufficient intake of folate may increase the risk of colorectal, breast, ovarian, pancreas, brain, lung, cervical, and prostate cancers. Folic acid acts on megaloblastic bone marrow to produce a normoblastic marrow. Molecular Formula C 19 H 19 N 7 O 6; Average mass 441.397 Da; Monoisotopic mass 441.139679 Da; ChemSpider ID 5815 [99], The risk of toxicity from folic acid is low, because folate is a water-soluble vitamin and is regularly removed from the body through urine. Folic acid is used for preventing and treating low blood levels of folate (folate deficiency), as well as its complications, including “tired blood” (anemia) and the inability of the bowel to absorb nutrients properly. This four electron reduction proceeds in two chemical steps both catalyzed by the same enzyme, dihydrofolate reductase. [59] However, methotrexate can be toxic,[60][61][62] producing side effects such as inflammation in the digestive tract that make eating normally more difficult.

The United States Department of Agriculture, Agricultural Research Service maintains a food composition database from which folate content in hundreds of foods can be searched as shown in the table. English: structure of folic acid with unknown number of glutamic acid. Folinic acid, under the drug name leucovorin, a form of folate (formyl-THF), can help "rescue" or reverse the toxic effects of methotrexate. [70], Some evidence links a shortage of folate with clinical depression. [68][67][69], A 2017 meta-analysis found that the relative risk of autism spectrum disorders was reduced by 23% when the maternal diet was supplemented with folic acid during pregnancy. Folic acid has a different structure and slightly different biological effects than folate. Folic acid synthesis protein fol1 (fol1) no protein annotated in this organism; This subpathway is part of the pathway tetrahydrofolate biosynthesis, which is itself part of Cofactor biosynthesis. Incompatible with heavy metal ions, strong oxidizing agents, strong reducing agents.Solutions may be light and heat sensitive.
