N-Acetyl Groups in Wool and Extracted Wool Proteins

Abstract

N . acetyl groups have been shown to exist in wool and in proteins extracted from wool after reduction with mercaptoethanol followed by alkylation with iodoacetate or after oxidation with performic acid. The evidence suggests that these acetyl groups are located on N-terminal amino groups of peptide chains rather than on the E-amino groups of lysine.</jats:p
