Glucagon, a polypeptide with diverse effects on the gastrointestinal tract (including the liver), plays a role in metabolic control. Glucagon raises cyclic adenosine monophosphate (AMP) levels via noncatecholamine mechanisms and therefore has direct inotropic properties. Furthermore, glucagon can release catecholamines from a pheochromocytoma and can be used to increase cardiac contractility, especially in the
