The Amino Acid Composition of Keratins II. The Amino Acid Composition of a Keratin Derivative Extracted From Wool With Alkaline Thioglycollate Solution

Abstract

The amino acid composition of a protein component of Merino 64's quality wool, which moves as a single peak on electrophoresis in alkaline thioglycollate solutions, has been determined. The results, which are summarized in Table 1, show that the purified protein fraction contains more aspartic acid, glutamic acid, leucine, lysine, and amide nitrogen, and less cystine, proline, serine, and tryptophan, than the parent wool from which it was extracted.
