In order to obtain some information regarding to the change in amino acid compositions of wool keratin brought about by hydrogen peroxide under conditions in which the Cu (II) ion is bound to wool, the amino acid analyses were made on the residues and the soluble pepetide fragments produced by this oxidation.
Cystine was converted into cysteic acid by this oxidation and not detected on the soluble pepetide fragments in filtrates. A relatively large amount of aspartic and glutamic acids was present in the residues and the filtrates. However phenylalanine and tyrosin were not detected in the filtrates, and these amino acids were less in the residues.
