CHARACTERIZATION OF AN ANTITHROMBOTIC PEPTIDE FROM KAPPA-CASEIN IN NEWBORN PLASMA AFTER MILK INGESTION

Bovine and human kappa-caseinoglycopeptides, two antithrombotic peptid es derived from the corresponding kappa-caseins, were detected in phys iologically active concentrations in the plasma of 5-d-old newborn inf ants after ingestion of cow's-milk-based formula or human milk respect ively. It is suggested that these two bioactive peptides are released from milk proteins during digestion.
