[21] Within cells, cyanocobalamin is converted to methylcobalamin and 5- deoxyadenosylcobalamin, coenzymes that participate respectively in homocysteine remethylation to methionine and in the isomerization of methylmalonyl-CoA to succinyl CoA, reactions essential for DNA synthesis, erythropoiesis, and myelin maintenance
