Introduced: January 1985

Description

Peptides and their preparation, purification, and characterization methods, including polypeptides, proteins, and enzyme substrates. This subclass covers synthesis routes (chemical and biological), isolation techniques, structural modifications, and analytical procedures for peptide compounds. It encompasses both naturally occurring peptides and synthetic derivatives, but excludes living organisms and their cultivation, which fall under biotechnology classes.
