What Does Glucagon Do: 7 Key Functions of This Peptide Hormone

Abstract: Glucagon, a 29-amino acid peptide hormone, primarily counteracts hypoglycemia by stimulating hepatic glycogenolysis and gluconeogenesis. In the peptide market, its synthetic analogs (e.g., GlucaGen, Baqsimi) dominate emergency diabetes care. Key technical advantages include rapid onset (1-2 min IV) and nasal delivery; disadvantages are short half-life (<10 min) and hyperglycemic rebound risk. Brands differ in stability (lyophilized vs. liquid) and delivery devices. Current industry trends show a 7.2% CAGR in peptide therapeutics, driven by dual-action GLP-1/glucagon agonists for obesity. Product selection requires verifying GMP-certified facilities, purity (>98% HPLC), and cold-chain logistics (2-8°C).
