Glucagon (CAS NO.16941-32-5) is described glucagon by Kimball and Murlin in 1923.The amino acid sequence of glucagon was described in the late-1950s. When a specific radioimmunoassay was developed,a more complete understanding of its role in physiology and disease was not established until the 1970s.

6. Production of Glucagon
Glucagon (CAS NO.16941-32-5) is synthesized from alpha cells (α-cells) of the islets, which are located in the endocrine portion of the pancreas.

7. Uses of Glucagon
Glucagon is used as antihyperglycemic. It helps maintain the level of glucose in the blood by binding to glucagon receptors on hepatocytes and is dependent on the central nervous system through pathways that are yet to be defined. Mechanism of action.And alsoit binds to the glucagon receptor, a G protein-coupled receptor located in the plasma membrane.
