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). [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. In dog breeds at risk for cleft lip and cleft palate dietary folic acid supplementation significantly decreased incidence. [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. If generated, an InChI string will also be generated and made available for searching. Wills demonstrated that anemia could be reversed with brewer's yeast.

Chemical structure of folic acid (vitamin B 9). English: structure of folic acid with unknown number of glutamic acid. Folic acid is also used for other conditions commonly associated with folate deficiency, including ulcerative colitis, liver disease, alcoholism, and kidney dialysis. [16] The term "folic" is from the Latin word folium (which means leaf) because it was found in dark-green leafy vegetables. [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. Australia implemented the program in 2009. Public domain Public domain false false: Ich, der Urheberrechtsinhaber dieses Werkes, veröffentliche es als gemeinfrei. 6 and folic acid was obtained by diluting 0.4 ml of standard stock solution of B 1, 0.8 ml of standards stock solution of B 3, 0.2 ml of standard stock solution of B 6 and 0.8 ml of standard stock solution of folic acid to 10 ml with 15 % methanol solution. [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. [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. 5-MTHF also plays both direct and indirect roles in DNA methylation, NO2 synthesis, and one-carbon metabolism. [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. For this reason, bacteria must synthesize folic acid from PABA. [112] For foods that are normally consumed cooked, values in the table are for folate naturally occurring in cooked foods. [105][106] Compliance with the updated labeling regulations was required by 1 January 2020 for manufacturers with US$10 million or more in annual food sales, and by 1 January 2021 for manufacturers with lower volume food sales. 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. [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. All plants and fungi and certain protozoa, bacteria, and archaea can synthesize folate de novo through variations on the same biosynthetic pathway. Normal MMA levels indicate folate deficiency and elevated MMA levels indicate vitamin B12 deficiency. The antifolate drug methotrexate is often used to treat cancer because it inhibits the production of the active tetrahydrofolate (THF) from the inactive dihydrofolate (DHF). 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. Pterin is in turn derived in a series of enzymatically catalyzed steps from guanosine triphosphate (GTP), while para-aminobenzoic acid is a product of the shikimate pathway. The EFSA reviewed the safety question and agreed with United States that the UL be set at 1,000 μg. It is used as it is more stable during processing and storage. One DFE is defined as 1 μg of dietary folate. [47][48], Chronically insufficient intake of folate may increase the risk of colorectal, breast, ovarian, pancreas, brain, lung, cervical, and prostate cancers. Comparing low to high dietary folate showed a modest but statistically significant reduced risk of colon cancer.

[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. Folate derivatives participate in the biosynthesis of both purines and pyrimidines. The active coenzyme form is tetrahydrofolate (THF). [7] Folate is required for the body to make DNA and RNA and metabolise amino acids necessary for cell division. [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. Serum folate reacts more rapidly to folate intake than erythrocyte folate. [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. Wills demonstrated that anemia could be reversed with brewer's yeast. [1] Symptoms may include feeling tired, heart palpitations, shortness of breath, open sores on the tongue, and changes in the color of the skin or hair. It is readily converted to other reduced folic acid derivatives (e.g., tetrahydrofolate), and, thus, has vitamin activity that is equivalent to that of folic acid. Methyl-THF converts vitamin B12 to methyl-B12 (methylcobalamin). [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. [90], Valproic acid, one of the most commonly prescribed epilepsy treatment drugs, also used to treat certain psychological conditions such as bipolar disorder, is a known inhibitor of folic acid, and as such, has been shown to cause birth defects, including neural tube defects, plus increased risk for children having cognitive impairment and autism. Folic acid is seen in the liver and kidney of the human. Folinic acid, under the drug name leucovorin, a form of folate (formyl-THF), can help "rescue" or reverse the toxic effects of methotrexate. There is evidence that folate consumption is protective. [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. Folic acid helps your body produce and maintain new cells, and also helps prevent changes to DNA that may lead to cancer. [8][80], Animals, including humans, cannot synthesize folate and therefore must obtain folate from their diet.

RNA transcription and subsequent protein synthesis are less affected by folate deficiency, as the mRNA can be recycled and used again (as opposed to DNA synthesis, where a new genomic copy must be created). [79], The biological activity of folate in the body depends upon dihydrofolate reductase action in the liver which converts folate into tetrahydrofolate (THF). In the 1920s, scientists believed folate deficiency and anemia were the same condition. Molecular Formula C 19 H 19 N 7 O 6; Average mass 441.397 Da; Monoisotopic mass 441.139679 Da; ChemSpider ID 5815 The requirement was set at 135 µg of folate per 100 g of bread. The amount of folate given is quickly depleted by rapidly dividing (cancer) cells, so this does not negate the effects of methotrexate. In the late 1930s, folate was identified as the corrective substance in brewer's yeast. Folic acid colour ranges from yellow to orange and is a tasteless needle-like crystal. 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. Folate is especially important during periods of frequent cell division and growth, such as infancy and pregnancy. The Centers for Disease Control and Prevention reported in 2015 that since the addition of folic acid in grain-based foods as mandated by the FDA, the rate of neural tube defects dropped by 35%.
