Vitamin B12 (cyanocobalamin)

Vitamin B12 is a water-soluble vitamin with roles in brain and nervous system functioning and blood formation through regulation of DNA synthesis, cellular metabolism, fatty acid metabolism, and amino acid metabolism.


Vitamin B12 belongs to the corrinoid group of compounds, which contain a corrin macrocycle, and is produced only by certain bacteria and archaea. Reference to vitamin B12 usually encompasses a group of cobalt-containing compounds (or cobalamins), which include cyanocobalamin, hydroxocobalamin, 5'-deoxyadenosylcobalamin (AdoB12), and methylcobalamin (MeB12). These forms serve as cofactors in isomerase-, methyltransferase-, andehalogenase-catalysed reactions.
