Coined/History
(?)
Glucose was discovered in 1747 by German chemist Andreas Marrgraf (1709-1782), who isolated it in raisins. In 1838 French chemist Jean-Baptiste Dumas (1800-1884) coined the term glucose and finally the structure of molecule was identified by German chemist and recipient of the Nobel Prize Emil Fischer (1852?1919).

Definition
Glucagon is a hormone produced by cells in the islets of Langerhans, having an opposite effect of insulin. The main role of glucagon is to promote glycogenolysis raising the blood glucose levels maintain normal concentrations of glucose in blood .






- #113 The Control Of Blood Glucose
The blood glucose concentration is regulated by negative feedback control mechanisms. Blood glucose concentration should remain at a fairly constant value of about 100 mg glucose per 100 cm3 of blood. If blood glucose concentration falls well below...
