Vitamin B12 consists of a class of chemically related compounds (vitamers), all of which have vitamin activity.
It contains the biochemically rare element cobalt sitting in the center of planar tetra-pyrrole ring called a Corrin ring.
Biosynthesis of the basic structure of the vitamin is accomplished only by bacteria and archaea
(which usually produce hydroxocobalamin), but conversion between different forms of the vitamin can be accomplished
in the human body.)
Usage:
Prototype of the family of naturally occurring cobalt coordination compounds knows as corrinoids. Analogs of vitamin B12 which differ only in the β -ligand of the cobalt are termed cobalamins. Synthesi zed almost exclusively by bacteria. Dietary sources include fish, meat, liver, and dairy products; Plants have little or no cobalamins. Converted by the body into its bioactive forms, methylcobalamin and cobamamide, which serve as enzyme cofactors. Severe deficiency may result in megaloblastic anemia and/or neurological impairment.
