Studies on in vitro proteolysis of casein using dissolved trypsin or covalently bound to oxirane beads have shown that immobilization leads to a change in the peptide pattern of the resulting proteolysate. Experiments on the variation of the enzyme-s

Characterization of pancreatic casein plasteins. In the course of the plastein reaction hydrophobic peptides concentrate mainly in the aggregates (plasteins), whilst hydrophilic peptides remain in solution (supernatant). Liquid chromatographic and se
