False statement about folic acid?
Folic acid : 1.Folic acid acts as a carrier of one-carbon units. 2.The active form of folic acid (pteroyl glutamate) is tetrahydrofolate. 3.Sources: Leafy Green Vegetables, Legumes, Seeds, Liver, 4. The folates in foods may have up to seven additional glutamate residues linked by -peptide bonds. In addition, all of the one-carbon substituted folates may also be present in foods. 5. The extent to which the different forms of folate can be absorbed varies, and folate intakes are calculated as dietary folate equivalents--the sum of g food folates + 1.7 x g of folic acid (used in food enrichment). 6.Prevents NTD in the fetus, and Lowers homocysteine. 7.Metabolism: The one-carbon fragment of methylene-tetrahydrofolate is reduced to a methyl group with the release of dihydrofolate, which is then reduced back to tetrahydrofolate by dihydrofolate reductase.
