Cholecystokinin-33 (1-21) (porcine)
Cholecystokinin-33 (1-21) (porcine) is a 21-amino-acid A peptide related to the cholecystokinin (CCK) family, which regulates gallbladder contraction, pancreatic enzyme secretion, satiety, and anxiety-like behavior through CCK-A and CCK-B receptors. Used in gastrointestinal, metabolic, and neuroscience research for studying digestive physiology, appetite regulation, and anxiogenic/anxiolytic mechanisms.
