Summary of folate metabolism (simplified). The schematic diagram shows that after entry of synthetic FA or natural dietary folates through receptors/carriers in cell membrane, the intracellular folate/ FA pass through series of biochemical reactions, and alter DNA methylation. Abbreviations: DHFR, dihydrofolate reductase; DHF, dihydrofolate; THF, tetrahydrofolate; SHMT, serine-hydroxymethyltransferase; 5,10-methenyl- THF, 5,10-methenyl-tetrahydrofolate; MTHFR, 5,10-methylenetetrahydrofolate reductase; 5-methyl THF, 5-methyltetrahydrofolate; MS, methionine synthase; B12, vitamin B-12; SAM, S-adenosylmethionine; SAH, S-adenosylhomocysteine; DNMT, DNA methyltransferase; MT, methyltransferases.
