Modifications of some peptic alfalfa leaf protein peptides as a result of plastein reaction with immobilized alpha chymotrypsin



Modifications of some peptic alfalfa leaf protein peptides as a result of plastein reaction with immobilized alpha chymotrypsin



Zeitschrift fuer Lebensmittel-Untersuchung und -Forschung 175(4): 249-252



Changes in peptides and their amino acid composition that take place during the plastein reaction carried out with immobolized .alpha.-chymotrypsin as a catalyst and with the low MW peptide fraction of alfalfa (Medicago sativa) leaf protein hydrolyzate as substrate were studied. By thin-layer fingerprint chromatography the substrate and the plastein reaction product exhibited 5 and 6 peptide species, respectively. The analysis of their amino-acid composition indicated that the substrate peptides in 2 cases gave rise to plastein peptides by slight apparent compositional changes; in the other cases they underwent more pronounced modifications.
