The change from homocysteine to methionine is one methyl group, by which is received from methyltetrahydrofolate (MTHF), a product of Methylenetetrahydrofolate reductase (MTHFR), as the methyl donor and a protein-bound B-12 vitamin Cobalamin as the methyl carrier. | The change from homocysteine to methionine is one methyl group, by which is received from methyltetrahydrofolate (MTHF), a product of Methylenetetrahydrofolate reductase (MTHFR), as the methyl donor and a protein-bound B-12 vitamin Cobalamin as the methyl carrier. | ||
