Beta Casomorphin 1-3 Peptide (Cat. No. 350596) corresponds to aa66-68 of human beta casein sequence and is conserved with the bovine 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.Human: H-Tyr-Pro-Phe-OH or H-YPF-OH
