multimer

This term is used exclusively within scientific registers, specifically in biochemistry, molecular biology, and polymer chemistry. It describes a specific structural arrangement where multiple identical or different subunits associate to form a larger functional unit. It is often contrasted with a monomer, which is a single subunit.

In a laboratory context, the term implies a focus on the stoichiometry and quaternary structure of a complex. While it describes a physical entity, it is used as a technical classification rather than a general descriptive term for any group of molecules.
