The two bioactive forms of vitamin {{chem|B|12}} are [[methylcobalamin]] in [[cytosol]] and [[adenosylcobalamin]] in [[mitochondria]]. Multivitamins often contain cyanocobalamin, which is presumably converted to bioactive forms in the body. Both methylcobalamin and adenosylcobalamin are commercially available as supplement pills. The [[MMACHC]] gene product catalyzes the decyanation of cyanocobalamin as well as the dealkylation of alkylcobalamins including methylcobalamin and adenosylcobalamin. This function has also been attributed to [[Cyanocobalamin reductase (cyanide-eliminating)|cobalamin reductases]]. The MMACHC gene product and cobalamin reductases enable the interconversion of cyano- and alkylcobalamins.</div>FuzzyBot
