What Are Research Peptides?
Research peptides are synthetic amino acid chains — typically between 2 and 50 residues in length — produced under controlled laboratory conditions for use in scientific investigation. They are distinct from pharmaceutical drugs, dietary supplements, and naturally occurring peptides.
Biochemistry & Structure
Peptides are formed through peptide bonds — covalent linkages between the carboxyl group of one amino acid and the amino group of the next. The sequence of amino acids determines the three-dimensional structure, which determines receptor binding specificity.
How Research Peptides Work
Research peptides exert their biological effects primarily through receptor binding — a lock-and-key interaction where the peptide's three-dimensional structure complements a specific receptor on the cell surface, triggering an intracellular signaling cascade.
