About Vitamin B12
Vitamin B12 is a family of cobalt-containing corrinoid compounds, collectively called cobalamins. Common forms include cyanocobalamin, hydroxocobalamin, methylcobalamin and adenosylcobalamin; the last two are the coenzyme forms that act inside cells.
The supplier list names this material only as “B-12”, so the specific cobalamin form must be confirmed on the lot documents. The form matters for stability, light sensitivity and behavior in assays.
Research context
In mammals, cobalamin is a cofactor for two enzymes: methionine synthase, which links folate and methionine metabolism, and methylmalonyl-CoA mutase, which works in mitochondrial propionate metabolism. It is used in research on one-carbon metabolism and methylation, and as a component of cell-culture media.
