Abstract
As we know, corrinoids are a family of tetrapyrrole pigments that perform vital functions in living systems, being called “pigments of life” (Battersby, 1985); chlorophyll, hemoglobin, cytochromes and vitamin B12 fall in this category. Metal ions in these pigments are complexed with organic ligands. In the coenzyme forms of vitamin B12 (AdoCbl and CH3Cb1) there is a direct bond between cobalt and carbon atoms. The two coenzymes of vitamin B12, also referred to as cobamides, are the only organometallic compounds found in living organisms. AdoCbl is a unique biocatalyst. Organometallic compounds with Co-C bonds are usually very unstable; in contrast, AdoCbl is one of the most stable complexes of transient metals (Schrauzer, 1968).
