Cholecystokinin Precursor (107-115) (human) (desulfated)

Cholecystokinin (CCK), also called pancreozymin, is a peptide hormone in the small intestine that constitutes the classical gut hormone triad together with gastrin and secretin1. CCK is secreted into the blood following ingestion of a meal and plays a critical role in the ingestion, absorption, intestinal motility, satiety signaling, inhibition of gastric acid secretion and digestion of food1.
