What is Vitamin B12?
Vitamin B12 (cobalamin) is an essential cofactor used in laboratory research as a reference compound for one-carbon and propionate metabolism, and as a co-component of lipotropic research blends.
Mechanism of action
Cofactor for methionine synthase and methylmalonyl-CoA mutase in one-carbon and propionate metabolism.
Primary research areas
One-carbon metabolism, methylation and lipotropic research models.
Research notes
- Standard component of MIC / Lipo-C lipotropic research blends.
- Methylcobalamin and cyanocobalamin forms differ in cofactor handoff kinetics.
