Xenin-25, Human

Xenin-25 is a gastrointestinal peptide originally isolated from human gastric mucosa. It influences intestinal motility, pancreatic secretion and glucose-dependent insulinotropic signaling and is studied in gut-brain and metabolic physiology.

• gastrointestinal hormone research
• incretin and metabolic signaling
• gut-brain axis studies
• GPCR and endocrine pharmacology

Exact peptide boundaries and C-terminal amidation are integral to product identity. In incretin studies, distinguish intact bioactive hormones from DPP-4-cleaved metabolites and analogs.
