DEFINITION

Classification: 516/44

The compound contains plural peptide linkages, i.e., compound formed from amino acids, natural or synthetic, by reaction of a carboxyl group of one such amino acid with an amino group of another same or different such amino acid:

(under subclass 43) Subject matter in which the organic* compound which contains nitrogen contains 2 or more peptide linkages, i.e., compound formed from natural or synthetic amino acids, such as casein, or glue.
