Cholecystokinin ( also known as CCK or CCK-PZ) is a peptide hormone of the gastrointestinal system which is responsible for stimulating the digestion of fat and protein. Along with gallbladder contraction, the effects of CCK on pancreatic secretion were demonstrated in the first half of the 20 th century when this hormone was also known as pancreozymin (29). When injected intravenously, sincalide stimulates gallbladder contraction and reduction in size. Cholecystokinin, otherwise known as CCK or CCK-PZ, is a hormone that was once called pancreozymin because of its actions on the pancreas.

Cholecystokinin (CCK) Like GLP-1, cholecystokinin (CCK) is another satiety hormone produced by cells in your gut ( 98 ). what does CCK? CCK is secreted by cells lining the upper intestine and by the hypothalamus. Cholecystokinin's most recognized function is its ability to improve digestion. The hormone reduces the rate at which food empties from the stomach, also stimulating bile production in the liver. Bile shrinks the fat droplets, enabling enzymes to more readily break them down. How many human teeth appear twice during the life span of an individual ?
