Cas no 22840-03-5 (Cholecystokinin Octapeptide (1-2) (desulfated) H-Asp-Tyr-OH)

Cholecystokinin Octapeptide (1-2) (desulfated), H-Asp-Tyr-OH, is a synthetic peptide fragment derived from the N-terminal sequence of cholecystokinin (CCK). This desulfated variant lacks the sulfate group typically present on the tyrosine residue, altering its biochemical properties. The peptide is of interest in research applications, particularly in studying CCK receptor interactions and signal transduction pathways. Its simplified structure allows for precise investigations into the role of sulfation in peptide-receptor binding and activity. The product is characterized by high purity and stability, making it suitable for in vitro and in vivo studies. Researchers value its utility in exploring gastrointestinal and neurological functions linked to CCK.
