CCK Octapeptide (sulfated)

Cholecystokinin (CCK) octapeptide is a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. It is a cleaved product of the full CCK preprohormone that is more potent than the full length enzyme in stimulating contraction of guinea pig gallbladder but with a shorter duration. CCK octapeptide (sulfated) is 300-fold more active than the non-sulfated CCK octapeptide (Cay-24404).Formal Name: 5-L-methionine-3-10-caerulein. CAS Number: 25126-32-3.
