Clinical Concept
Peptide
A short chain of amino acids — longer than a single amino acid, shorter than a full protein — that acts as a precise biological signal.
Definition
Peptides are chains of two to roughly fifty amino acids linked by peptide bonds. Their small size and specific sequence let them bind receptors with much greater selectivity than most small-molecule drugs. The human body produces thousands of endogenous peptides — signalling hormones like insulin and oxytocin, immune modulators, antimicrobial peptides, growth factors. Therapeutic peptides are synthetic analogs of these natural signals.
