Liraglutide- Summary
- PGPIPN is a bioactive hexapeptide (Pro-Gly-Pro-Ile-Pro-Asn) derived from beta-casein during enzymatic digestion. It exhibits anti-inflammatory properties via opioid receptor modulation and cytokine suppression, making it relevant for gut health, systemic inflammation, and as a component of casein-derived functional foods.
- Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.
- Half-Life
- Estimated 30-120 minutes (peptide degradation)
- ~13 hours (once-daily dosing)
- Admin Route
