In reverse, niacin is necessary for the synthesis of vitamin B6 (pyridoxine) and riboflavin, as well as vitamin B9 (folate) [ 56, 57, 63 ]. WebAug 1, 2002 · Folate, as 5,10 methylene THF, donates a methyl group to uracil converting it to thymine, which is used for DNA synthesis and repair. However, if folate is limiting, uracil misincorporation into DNA may occur. This in itself is mutagenic, but DNA instability also may occur via a different mechanism. chicago kringle market
