Common NameCeruletide
DescriptionCeruletide, also known as caerulein, is only found in individuals that have used or taken this drug. It is a specific decapeptide similar in action and composition to the natural gastrointestinal peptide hormone cholecystokinin. It stimulates gastric, biliary, and pancreatic secretion; and certain smooth muscle.Ceruletide acts according to its similarity to the natural gastrointestinal peptide hormone cholecystokinin. Cholecystokinin is a peptide hormone of the gastrointestinal system responsible for stimulating the digestion of fat and protein. Cholecystokinin is secreted by the duodenum, the first segment of the small intestine. There it binds to CCK receptors, activating them and causing downstream effects. Specifically, it results in the release of digestive enzymes and bile from the pancreas and gall bladder, respectively. It also acts as a hunger suppresant. Cholecystokinin is secreted by the duodenum when fat- or protein-rich chyme leaves the stomach and enters the duodenum. The hormone acts on the pancreas to stimulate the secretion of the enzymes lipase, amylase, trypsin, and chymotrypsin. Together these pancreatic enzymes catalyze the digestion of fat and protein. Cholecystokinin also stimulates both the contraction of the gall bladder, and the relaxtion of the Sphincter of Oddi (Glisson's Sphinctor), which delivers, (not secretes) bile into the small intestine. Bile salts serve to emulsify fats, thereby increasing the effectiveness with which enzymes can digest them.

Enzymes

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Receptor for cholecystokinin. Mediates pancreatic growth and enzyme secretion, smooth muscle contraction of the gall bladder and stomach. Has a 1000-fold higher affinity for CCK rather than for gastrin. It modulates feeding and dopamine-induced behavior in the central and peripheral nervous system. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system
