Description

General description

Vitamin B₁₂ cobalamin refers to a group of chemically-related cobalt containing molecules. The physiologically active forms of vitamin B₁₂ include methylcobalamin and adenosylcobalamin, whereas hydroxocobalamin (vitamin B_12a, OHCbl) and cyanocobalamin (CNCbl) are storage and delivery forms.

Application

Coenzyme B₁₂ has been used as a supplement for culturing plasmid variants in in vivo assay of yvrC-lacZ fusions.

Biochem/physiol Actions

Vitamin B₁₂ cobalamin is involved in DNA synthesis and fatty acid synthesis. It also plays a vital role as a coenzyme in the conversion of mitochondrial methylmalonyl co-enzyme A to succinyl co-enzyme A.
