corrinoid

This term is used exclusively within specialized biochemical and organic chemistry contexts. It describes a specific class of cobalt-containing macrocycles, serving as a broader category that encompasses cobalamins (such as vitamin B12) and their synthetic or biological precursors.

As a technical descriptor, the adjective form is typically used to modify proteins, enzymes, or chemical structures (e.g., corrinoid proteins), indicating a structural relationship to the corrin ring. It is not used in general conversation or non-scientific literature.
