Roles Classification
Biological Roles:
cofactor  An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. It may be attached either loosely (coenzyme) or tightly (prosthetic group).
human metabolite  Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
prosthetic group  A tightly bound, specific nonpolypeptide unit in a protein determining and involved in its biological activity.
metabolite  Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
cofactor  An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. It may be attached either loosely (coenzyme) or tightly (prosthetic group).
