In organic chemistry, peptide synthesis is the production of peptides, which are organic compounds in which multiple amino acids are linked via amide bonds, also known as peptide bonds. Peptides can be chemically synthesized by coupling the carboxyl group of one amino acid to the amino group of another amino acid molecule.

Well-known peptide families
The peptide families in this section are ribosomal peptides, usually with hormonal activity. All of these peptides are synthesized by cells as longer \"propeptides\" or \"proproteins\" and truncated prior to exiting the cell. They are released into the bloodstream where they perform their signaling functions.
Antimicrobial peptides
Tachykinin peptides
Vasoactive intestinal peptides
Pancreatic polypeptide-related peptides
Opioid peptides
Calcitonin peptides
Other peptides
