Peptides
Peptides play an essential role in fundamental physiological processes and are necessary for many biochemical processes. A peptide is a short string of 2 to 50 amino acids, formed by a condensation reaction, joining together through a covalent bond. Sequential covalent bonds with additional amino acids yield a peptide chain and the building block of proteins.
Peptides fall under the broad chemical classes of biological polymers and oligomers, alongside nucleic acids, oligosaccharides, polysaccharides, and others.
