Cholecystokinin (CCK)
Overview
Cholecystokinin (CCK), also known as pancreozymin, is a peptide hormone of the gastrointestinal system that stimulates the digestion of fats and proteins. Synthesized and secreted by enteroendocrine I cells in the duodenal mucosa, CCK triggers gallbladder contraction and bile release, stimulates pancreatic enzyme secretion, and suppresses appetite through vagal afferent signaling, making it a key regulator of digestive function and satiety.
