Cholecystokinin-33 (CCK-33) is a peptide hormone primarily involved in digestion and appetite regulation. It is produced in the small intestine and plays a crucial role in stimulating the gallbladder to contract and release bile, which aids in the emulsification and digestion of fats. CCK-33 also promotes the secretion of digestive enzymes from the pancreas and contributes to the sensation of satiety after meals. The substance is characterized by its sequence of amino acids, which defines its biological activity and specificity. As a member of the cholecystokinin family, CCK-33 exhibits various physiological effects, including modulation of gastrointestinal motility and influence on central nervous system functions related to hunger and fullness. The CAS number 96827-04-2 uniquely identifies this specific peptide, facilitating its recognition in scientific literature and databases. Overall, CCK-33 is significant in both digestive processes and potential therapeutic applications related to obesity and metabolic disorders.

Cholecystokinin-33 (human) trifluoroacetate

CCK-33 is a synthetic peptide that is used as a research tool. It binds to the CCK2 receptor and activates it, triggering the release of the neurotransmitter acetylcholine. CCK-33 is also an inhibitor of voltage-gated potassium channels, which are important for neuronal communication. CCK-33 can be used to identify other ligands for this receptor, or as an antibody epitope tag in cell biology studies.
