Read articlePeptides are short chains of amino acids linked by peptide bonds. Unlike proteins, which typically contain 50 or more amino acids, peptides are generally defined as having fewer than 50 amino acids, though this distinction can vary.
The biological activity of peptides depends on their specific amino acid sequence, which determines their three-dimensional structure and how they interact with cellular receptors. This structure-function relationship is fundamental to understanding how different peptides produce different effects.
