Product Description | Glucagon is a 29-amino acid peptide hormone secreted by pancreatic α-cells that raises blood glucose and (indirectly) insulin levels. Glucagon acts via a G protein-coupled receptor, which results in the release of glucose 1-phosphate from glycogen.. Glucagon-(19-29) is 1000-fold more potent that glucagon as an inhibitor of the liver plasma membrane calcium pump, which suggests that this peptide fragment is naturally occurring. Since glucagon-(19-29) is undetectable in plasma, the processing of glucagon into its (19-29) fragment may occur upon interaction of glucagon with its target tissues. |
