Peptide Compounds

Meaning

Peptide Compounds are short chains of amino acids linked together by peptide bonds, structurally defined as molecules typically containing fewer than fifty amino acid residues, distinguishing them from larger proteins. These compounds function as crucial signaling molecules in the human body, acting as hormones, growth factors, neurotransmitters, and antimicrobial agents, mediating a vast array of physiological processes. Their small size and specific sequence allow them to bind to and activate highly selective cell surface receptors.
