CCK (26-30) (sulfated) (N-Acetyl Cholecystokinin (26-30)) is primarily used in research to study the role of cholecystokinin (CCK) in the body. It is particularly valuable in neuroscience and gastrointestinal studies due to its ability to mimic the activity of the full CCK peptide. Researchers use it to investigate CCK's effects on appetite regulation, anxiety, and pain modulation, as it interacts with CCK receptors in the brain and digestive system. Additionally, it serves as a tool to explore the sulfation process and its impact on peptide function, providing insights into post-translational modifications. This compound is also utilized in developing therapeutic strategies for conditions like obesity, anxiety disorders, and gastrointestinal diseases.
