Vitamin B12 (Cobalamin) 10mg/10ml – Research Solution
Vitamin B12 (cobalamin) is an essential water-soluble vitamin and enzymatic cofactor central to one-carbon metabolism. In its active forms — methylcobalamin and 5-deoxyadenosylcobalamin — it serves as a cofactor for methionine synthase and methylmalonyl-CoA mutase, supporting methylation reactions, homocysteine metabolism, and cellular energy pathways studied in metabolic and nutritional research.
