WebCCK has a biologically active C-terminal pentapeptide. CCK exists as a larger precursor hormone, preproCCK (114 amino acids), from which several smaller fragments are derived, sharing a C-terminal tetrapeptide and a sulfated tyrosine residue. Sulfated CCK (26-33) amide (CCK-8) is the major and the most potent CCK form in the brain and periphery. WebCholecystokinin. Cholecystokinin (CCK) is a hormone secreted by the I-cells of the upper small intestine in response to fat, protein, and some nonnutrients, for example, camostat, and a peptide/neurotransmitter secreted by neurons of the central and peripheral nervous systems.
