Description
Glucagon is a peptide hormone with a molecular weight of 3,485 consisting of 29 amino acid residues, secreted by the alpha cells of the pancreas. It acts on the liver to promote the production and release of glucose through glycogenolysis and glycogenesis, thereby raising blood glucose. It has been indicated that dysregulation of glucagon secretion is important in the pathogenesis of diabetes as it is involved with insulin in the regulation of glucose homeostasis. Proglucagon, a precursor of glucagon produces similar peptides such as glicentin and oxyindomodulin, which have amino acid sequences that overlap with glucagon by different processing process depending on the produced cell
