(under subclass 86) Subject matter in which (a) the specie of interest is an organic compound that contains both a basic amino group and a acidic carboxyl group or (b) a process of analysis of a peptide in which the identity and order of the amino acid residues in the peptide are determined.
(1) Note. The peptide need not be completely sequenced; a procedure to determine as few as two units would be properly classifiable herein.
