Общее описание

It was thought originally that cholecystokinin and pancreozyminwere two different hormones. Cholecystokinin wasthought to be responsible for contraction of the gallbladder,whereas pancreozymin was believed to induce secretion ofpancreatic enzymes. It is now clear that both actions arecaused by a single 33-residue polypeptide, referred to ascholecystokinin–pancreozymin (CCK-PZ). CCK-PZ is secretedin the blood in response to the presence of food in theduodenum, especially long-chain fatty acids. The fiveCOOH-terminal amino acid residues are identical with thosein gastrin. The COOH-terminal octapeptide retains full activityof the parent hormone.
