CCK identified at bottom right. Cholecystokinin (CCK or CCK-PZ; from Greek chole, bile; cysto, sac; kinin, move; hence, move the bile-sac (gallbladder)) is a peptide hormone of the gastrointestinal system responsible for stimulating the digestion of fat and protein.CK is composed of varying numbers of amino acids depending on post-translational modification of the CCK gene product, preprocholecystokinin. Thus CCK is actually a family of hormones identified by number of amino acids, e.g., CCK58, CCK33, CCK22 and CCK8.
