Cholecystokinin Precursor (24-32) (rat) (Cat No.: I037921) is a nonapeptide sequence derived from the prohormone form of cholecystokinin (CCK) in rats. This fragment represents a segment involved in the post-translational processing of CCK, a hormone crucial for digestion and satiety signaling. Studying this precursor peptide helps elucidate the biosynthesis, maturation, and regulatory pathways of CCK in the central nervous system and gastrointestinal tract. It is commonly used in neuroendocrine and metabolic research to explore CCK’s role in appetite control and digestive enzyme regulation.
