WebSep 28, 2024 · Found in low levels across most food products of plant origin and found in enhanced levels in some nation's wheat grain due to fortification, folic acid is a vitamin that has essential roles in the growth of neonates as well as in supporting a process known as methylation in adults. WebTetrahydrofolic acid ( THFA ), or tetrahydrofolate, is a folic acid derivative. Metabolism [ edit] Human synthesis [ edit] Tetrahydrofolic acid is produced from dihydrofolic acid by dihydrofolate reductase. This reaction is inhibited by methotrexate. [1] It is converted into 5,10-methylenetetrahydrofolate by serine hydroxymethyltransferase .
