Common Name | Methylcobalamin |

Description | The name vitamin B12 is used in two different ways. In a broad sense it refers to a group of cobalt-containing compounds known as cobalamins - cyanocobalamin (an artifact formed as a result of the use of cyanide in the purification procedures), hydroxocobalamin and the two coenzyme forms of B12, methylcobalamin (MeB12) and 5-deoxyadenosylcobalamin (adenosylcobalamin - AdoB12). In a more specific way, the term B12 is used to refer to only one of these forms, cyanocobalamin, which is the principal B12 form used for foods and in nutritional supplements. B12 cannot be made by plants or by animals, as the only type of organisms that have the enzymes required for the synthesis of B12 are bacteria and archaea. The total synthesis of B12 was reported in 1973 by Robert Burns Woodward, and remains one of the classic feats of total synthesis. Cyanocobalamin is a vitamin commonly known as vitamin B12 (or B12 for short). |
