Cholecystokinin fragment 1-21, also known as CCK-8, is a peptide that plays a crucial role in digestion and appetite regulation. It is derived from the larger cholecystokinin molecule, which is produced in the small intestine. This fragment consists of 21 amino acids and is involved in stimulating the gallbladder to contract and release bile, as well as promoting the secretion of digestive enzymes from the pancreas. Additionally, CCK-8 is known to influence satiety signals in the brain, thereby regulating food intake. The CAS number 101831-07-6 specifically identifies this peptide, which is often used in research settings to study gastrointestinal function and neuroendocrine signaling. Its biological activity is attributed to its interaction with specific receptors, primarily the CCK-A and CCK-B receptors, which are distributed throughout the gastrointestinal tract and central nervous system. Overall, cholecystokinin fragment 1-21 is significant in both digestive processes and the modulation of appetite.
