Abstract: Glucagon, a 29-amino acid peptide hormone, primarily raises blood glucose by stimulating hepatic glycogenolysis. Its key functions include reversing hypoglycemia, inhibiting gastric motility, and promoting lipolysis. In the peptide market, synthetic glucagon analogs offer superior stability over bio-derived forms. Brands like Eli Lilly dominate, while Novo Nordisk leads in dual-action agonists. Regulatory certifications (FDA, GMP) are critical for product safety. Current trends show a 7.2% CAGR in peptide therapeutics, driven by diabetes and obesity applications.
