Amino Acid Chains

Meaning

Amino acid chains are linear polymers formed by multiple amino acid monomers covalently linked together by peptide bonds, representing the fundamental structural component of all peptides and proteins. The precise sequence of these units, dictated by genetic code, determines the subsequent complex three-dimensional folding of the molecule and its ultimate biological activity. In the endocrine system, these chains are the molecular architecture for peptide hormones, which function as crucial signaling messengers.
