Corrinoid

Corrin ring, numbered according to the 1975 IUPAC standard. Note that for consistency with the porphyrin numbering system, there is no 20 position. Positions 21-24 were numbered 20-23 in earlier literature.[1]

Corrinoids are a group of compounds based on the skeleton of corrin, a cyclic system containing four pyrrole rings similar to porphyrins. These include compounds based on octadehydrocorrin, which has the trivial name corrole.

The cobalamins (vitamin B₁₂) are the best known members of the group. Other prominent examples include cobyrinic acid and its hexaamide cobyric acid; cobinic acid and its hexaamide cobinamide; cobamic acid and cobamide.
