The prototype of the naturally occurring family of cobalt coordination compounds is called a morpholine.  The analogue of vitamin B12 differs only in the cobalt β -ligand and is called cobalamin.  It's made almost entirely by bacteria.  Dietary sources include fish, meat, liver, and dairy Chemicalbook;  Plants have little or no cobalamin.  The body converts it into biologically active forms called methylcobalamin and cobalamin, which act as enzyme cofactors.  Severe deficiency may result in megaloblastic anemia and/or neurological dysfunction.
