Part of the Basic Life Sciences book series


The caseins are the major proteins of milk providing needed amino acids to the suckling infant. The bovine caseins have been the most thor oughly studied and serve as the principal basis for the dairy industry. The bovine caseins are comprised of 4 major polypeptide families: αsl-, αs2-, ß-, and κ-caseins (52). They are phosphorylated to varying degrees generally containing 8, 10–13, 5, and one seryl phosphate residues per monomer, respectively. The fact that some molecules of κ-casein are also glycosylated while others do not contain carbohydrate residues gives rise to electrophoretic heterogeneity.
