A hormone formed in the pancreas which promotes the breakdown of glycogen to glucose in the liver.‘The classic interactions between receptors, G-protein transducer, and membrane-localized adenylate cyclase are illustrated below using the pancreatic hormone glucagon as an example.’
- ‘One of these molecules, glucose, is mainly controlled by the hormones insulin and glucagon that are released from the pancreas.’
- ‘There was no tumoral expression for serotonin, glucagon, insulin, gastrin, vasointestinal peptide, or pancreatic polypeptide.’
- ‘Glycemic control is maintained by a balance between insulin and the counterregulatory hormones glucagon, epinephrine, cortisol, and growth hormone.’
- ‘Overnight fasting can promote a rise in the muscle-disassembling hormones glucagon and cortisol.’
1920s from Greek glukus ‘sweet’ + agōn ‘leading, bringing’.
