Trimers The term trimeric peptide refers to a molecule composed of three peptide chains that associate to form a functional unit. This association can be either through non-covalent interactions, forming a macromolecular complex formed by three, usually non-covalently bound, macromolecules, or through covalent linkages, such as disulfide bonds, creating disulfide bond-linked homo-trimeric forms. The study of these structures is a dynamic field, with ongoing research exploring their diverse roles in biological systems and their potential applications in medicine and biotechnology.
