| Description: The molecule shown here is the cyanide-containing form originally isolated (cyanocobalamin). In cells, a water molecule or hydroxyl group takes the place of CN, forming the precursor to the coenzyme forms of B12. The corrin ring is shown in red. 5,6-Dimethylbenzimidazole (DMB), which is linked to the cobalt, is shown in blue.
