A dipeptide is a kind of organic compound (and therefore a kind of molecule). A dipeptide is made up of only two amino acids: one amino acid on each side of a peptide bond. A dipeptide can be made from two different amino acids or by two amino acids of the same kind. A peptide bond will be in between the two amino acids.
Gly-Gly, or Glycylglycine is a dipeptide and also the simplest peptide. It is the dipeptide of Glycine.
