Beta Casomorphin 1-4 Peptide (Bovine) (Cat. No. 350597) corresponds to aa75-78 of bovine beta casein sequence. Casomorphins are bioactive peptides derived from the digestion of beta-casein, a milk protein, with a role in micelle formation. There are associations between serum levels of beta-casomorphins and risk of sudden infant death syndrome, histamine release, stimulation of food intake, and lymphocytosis.Bovine: H-Tyr-Pro-Phe-Pro-OH or H-YPFP-OH
