Peptide facts for kids

A tetrapeptide (example Val-Gly-Ser-Ala) with green marked amino end (L-Valine) and blue marked carboxyl end (L-Alanine).

Peptides are organic chemical molecules. They are polymers made from linking amino acids together in a certain order. The link between one amino acid residue and the next is known as an amide bond or a peptide bond.

Linking peptides together gives proteins, which are also known as Polypeptides.
