Peptide

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 polypeptides.

Skeletal formula of Gly-Gly. The peptide bond is between the carbon that is double bonded to the oxygen, and the nitrogen.

Gly-Gly, or Glycylglycine is (a dipeptide and also) the simplest peptide; It is the dipeptide of Glycine.^[1]
