CCK 8 Octapeptide, sulfated, aka Cholecystokinin (26-33) is a C-terminal sulfated and amidated octapeptide of Cholecystokinin (CCK). It has the full biological action of the full-length 33-amino acid long CCK and is more potent than the non-sulfated CCK-8. CCK is found in the central nervous system and gastrointestinal tract and mediates satiety.
CCK 8 Octapeptide, sulfated is also known by its tradename, Sincalide.
