IUPAGIUB Combined Commission on Biochemical Nomenclature Abbreviated Nomenclature of Synthetic Polypeptides (Polymerized Amino Acids)1–3

c ommission On iochemie Nomenclature Nomenclature of Syut~etic esThe numerous studies on the physical, chemical, and biological properties of synthetic polypeptides have brought with them different ways of describing, in abbreviated form, these products, whose structures are often incompletely known.The the remaining hydrogen atom of the peptide bond, dependin upon their placement (4).L-Amino acids and a-peptide links, read from left (NH2 terminus) to right (COOH terminus), are assumed unless indicated otherwise (3,4).use of a variety of nomenclatures complicates the literature; hence, a consistent and clearly defined system for naming such polypeptides is desirable.The proposals set forth here, which De~n&on.s
