Research Overview
Secretin
Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
Lixisenatide
Lixisenatide produces small but measurable weight loss in diabetes trials while improving postprandial glucose excursions. Its shorter half-life makes it a useful reference compound for first-generation incretin mimetics.
