Chains of fewer than ten or fifteen amino acids are called oligopeptides and include dipeptides tripeptides and tetrapeptides. A polypeptide is a longer continuous unbranched peptide chain of up to approximately fifty amino acids. Hence peptides fall under the broad chemical classes of biological polymers and oligomers alongside nucleic acids oligosaccharides polysaccharides and others. A polypeptide that contains more than approximately fifty amino acids is known as a protein. Proteins consist of one or more polypeptides arranged in a biologically functional way often bound to ligands such as coenzymes and cofactors or to another protein or other macromolecule such as DNA or RNA or to complex macromolecular assemblies. Amino acids that have been incorporated into peptides are termed residues. A water molecule is released during formation of each amide bond. All peptides except cyclic peptides have an N-terminal (amine group) and C-terminal (carboxyl group) residue at the end of the peptide (as shown for the tetrapeptide in the image). Many kinds of peptides are known. They have been classified or categorized according to their sources and functions. According to the Handbook of Biologically Active Peptides some groups of peptides include plant peptides bacterial/ antibiotic peptides fungal peptides invertebrate peptides amphibian/skin peptides venom peptides cancer/anticancer peptides vaccine peptides immu… Many kinds of peptides are known. They have been classified or categorized according to their sources and functions. According to the Handbook of Biologically Active Peptides some groups of peptides include plant peptides bacterial/ antibiotic peptides fungal peptides invertebrate peptides amphibian/skin peptides venom peptides cancer/anticancer peptides vaccine peptides immune/inflammatory peptides brain peptides endocrine peptides ingestive peptides gastrointestinal peptides cardiovascular peptides renal peptides respiratory peptides opiate peptides neurotrophic peptides and blood–brain peptides. Some ribosomal peptides are subject to proteolysis . ...
