WebTHF and DHF are unsubstituted folate species which do not play a direct metabolic role, but rather receive one-carbon moieties and transfer them toward either methylation-dependent or DNA-synthesis-dependent pathways (Fig. 4.3, pool 4). DHF reductase is a critical enzyme that is responsible for reducing folic acid and DHF into the metabolically ... Web5,10-Methylenetetrahydrofolate (N5,N10-Methylenetetrahydrofolate; 5,10-CH 2-THF) is cofactor in several biochemical reactions.It exists in nature as the diastereoisomer [6R]-5,10-methylene-THF..
