| Definition | ChEBI: A cobalamin in which the central cobalt atom has an oxidation state of +3. | | Synthesis | In 1960, the research group of the biochemist Konrad Bernhauer in Stuttgart had reconstituted vitamin B12 from one of its naturally occurring derivatives, cobyric acid, by stepwise construction of the vitamin's nucleotide loop. Therefore, cobyric acid was chosen as the target molecule for a total synthesis of vitamin B12 (cobalamin).
