Classification of peptides

Release Time:2018-11-08 Back to list

According to source classification, polypeptides can be divided into bioactive polypeptides and synthetic polypeptides; according to size classification, they can be divided into small, medium and large peptides. Small peptides refer to polypeptides with the number of amino acid residues less than 15, medium peptides refer to polypeptides with the number of amino acid residues between 15 and 50, and polypeptides with the number of amino acid residues more than 50 are called large. Peptides can be classified into homopeptides and heteropolypeptides according to their structure. Homopolypeptides contain straight chain and cyclic peptides, and heteropolypeptides contain pigments, glycopeptides, lipopeptides and lipopeptides. According to functional classification, polypeptides can be classified into motor proteins, hormone proteins, toxic proteins, polypeptide hormones, enzyme proteins, polypeptide antibiotics and polypeptide antibiotics. Toxic peptide and so on.
