Peptides, Simplified

Peptides are short chains of amino acids — typically 2 to 50 — linked by peptide bonds. They occur naturally in the body and play roles in signaling, immune function, and tissue repair. Researchers study synthetic peptides to understand these biological processes. All information below is for educational and research purposes only.
