Methylcobalamin is an endogenous coenzyme B12. It plays an important role as a coenzyme of methionine synthase in the transmethylation reaction of methionine synthesized from homocysteine. It is easily transferred to the organelles of nerve cells, thereby promoting the synthesis of nucleic acids and proteins. It is easier to transfer into the organelles of rat nerve cells than cyanocobalamin. In experiments on brain cells and spinal cord nerve cells of mice, it participates in the process of synthesizing thymidine from deoxyuridine, promotes the utilization of folic acid and the metabolism of nucleic acids. It can promote the synthesis of nucleic acids and proteins in rats better than cobalamin. It promotes intra-axonal transport and axonal regeneration.
