Glucagon | C153H225N43O49S | CID 16132283 - PubChem
Glucagon is a 29 amino acid hormone used as a diagnostic aid in radiologic exams to temporarily inhibit the movement of the gastrointestinal tract and to treat severe hypoglycemia. Glucagon raises blood sugar through activation of hepatic glucagon receptors, stimulating glycogenolysis and the release of glucose. Glucagon was granted FDA ...

Molecule of the Month: Glucagon - RCSB: PDB-101
Several structures for isolated glucagon and modified forms of glucagon are available in the PDB, showing that it has a range of conformations in different environments. Try searching for "glucagon" to see a few of them.
Glucagon - Proteopedia, life in 3D
Glucagon (GLC) is a 29-residue peptide hormone that raises blood glucose levels. GLC causes , signalling the liver to convert glycogen to glucose. The effect of glucagon is opposite to that of insulin [1]. Cells sense the presence of glucagon when it binds the glucagon receptor, a G-protein coupled receptor.
Glucagon - an overview | ScienceDirect Topics
Glucagon is a single-chain polypeptide of 29 amino acids that has a structural homology with secretin, vasoactive intestinal polypeptide (VIP), and gastric inhibitory polypeptide (GIP). The glucagon structure is also contained within the sequence of glicentin (“gut glucagon”).
Physiology, Glucagon - StatPearls - NCBI Bookshelf
Glucagon, manufactured by the alpha cells in the pancreatic islets, stimulates glucose production through glycogenolysis and gluconeogenesis. Elevated plasma concentrations of glucagon and hyperglucagonemia contribute to the hyperglycemia of diabetes.
Glucagon:: Molecular Biology and Structure-Activity - ScienceDirect
1997年1月1日 · Glucagon is produced and processed from preproglucagon in pancreatic α cells, in small intestine L cells, and in certain hypothalamic cells (Schroeder et al., 1984; Tricoli et al., 1984). Preproglucagon consists of a signal peptide, glicitin-related polypeptide, glucagon (1-29), glucagon-like peptide-1 (GLP-I), and glucagon-like peptide-2 (GLP-2).
The past, present and future physiology and pharmacology of glucagon …
Glucagon acts through a specific glucagon receptor (GCGR), a class B G-protein coupled receptor (GPCR) that activates adenylate cyclase to raise intracellular cAMP. Activation of the protein kinase A (PKA) pathway by cAMP is generally agreed …
Chemists discover structure of glucagon fibrils | MIT News ...
2019年6月24日 · A study from MIT reveals the structure of glucagon fibrils and suggests possible strategies for altering the structure so that glucagon, which is used to treat hypoglycemia in diabetic patients, is less likely to become clumped.
