Glucagon is a 29-amino-acid polypeptide hormone secreted by pancreatic alpha cells that raises blood glucose by stimulating hepatic glycogenolysis and gluconeogenesis, counterbalancing insulin action. In research, it is used to model glucose counter-regulation, hepatic metabolism and receptor signaling at the glucagon receptor.
