Pharmacology
Folic acid as it is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase (DHFR). These folic acid congeners are transported across cell by receptor-mediated endocytosis where they are needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids methylate RNA and generate and use format. Using vitamin B12 as a cofactor. folic acid can normalize high homocysteine levels by remethylation of homocysteine to methionine via methionine synthetase.
