(Thr28,Nle31)-Cholecystokinin-33 (25-33) (sulfated) is a CCK-33 fragment carrying threonine and norleucine substitutions alongside a sulfated tyrosine. The sequence preserves the canonical C-terminal recognition motif of cholecystokinin. Modified residues influence local conformation and hydrophobic interactions. Researchers use it to define minimal determinants for CCK receptor binding and signaling.
