Glucagon is a hormone that is involved in controlling blood sugar (glucose) levels. It is secreted into the bloodstream by the alpha cells, found in the islets of Langerhans, in the pancreas. It stimulates the conversion of stored glycogen (stored in the liver) to glucose which can be released into the bloodstream. 2  This process is called glycogenolysis. 3  It promotes the production of glucose from amino acid molecules. 4  This process is called gluconeogenesis.
