Glucagon Usage And Synthesis
Polypeptide hormone with straight-chain Glucagon, also known as glucagon, is a straight-chain polypeptide hormone secreted by pancreatic islet α cells, containing 29 amino acids, with molecular formula and relative molecular mass of C153H225N43O49S = 3482.8. China has synthesize this hormone. It is a kind of white, odorless, and tasteless fine crystalline powder at room temperature. Glucagon is nearly insoluble in water and most organic solvents, while it is soluble in dilute acid and dilute alkali solution. Most of the preparation are hydrochloride which is dissolved in water. It is known that glucagon must retain its molecular integrity in order to exert its physiological activity. The glucagon structure of human and mammalian (rabbit, bovine, porcine, rat, etc.) may be consistent, while slightly different birds.
It is an important hormone to maintain normal blood glucose. The main role of glucagon is to activate the myocardium phosphorylation enzymes, promote glycogen breakdown and have a similar role of catecholamines. Therefore, it has a cardiac effect, making heart rate, myocardial contractility and coronary blood flow increased. Cardiac function is not associated with increased excitability of the heart, while it will make more calcium into the myocardial cells and can activate the adenylate cyclase of the liver cell membrane, thus promoting intracellular cyclization-synthesis of adenosine phosphate. Glucagon has been reported to be effective in certain heart failure cases. In addition, in the state of diabetes, liver disease, kidney disease, glucagon and stress, etc., the plasma levels are also increased to varying degrees. Glucagon owns four major physiological roles of the promotion of liver glycogen breakdown, glycogen gluconeogenesis, lipolysis and ketone body formation. It can promote the uptake of amino acids in liver cells, accelerat
