Action of Rennin on κ-Casein, the Amino Acid Compositions of the Para-κ-Casein, and Glycomacropeptide Fractions

Abstract

The action of rennin on κ-casein obtained from the milk of an individual cow was investigated. Polyacrylamide-gel electrophoresis at pH 9.2 indicated the presence of two major components in reduced para-κ-casein. The amino acid compositions of κ-casein, para-κ-casein, and the glycomacropeptide were compared. © 1965, American Dairy Science Association. All rights reserved.
