Based mostly on the variations of the variety of amino acids, these polypeptides are divided into dipeptides (including two amino acids), tripeptides (including three amino acids), tetrapeptides (together with 4 amino acids), and so on. Because of the different classes of amino acids contained, each dipeptides and tripeptides have different varieties. At the same time, even with the same variety of amino acids, the dipeptides will still have different varieties because of the totally different kind order of the amino acid.
