About Glucose Monosaccharide,Aldohexose, Nutritive,sweetner. Mechanism of Action of Glucose Glucose is a simple carbohydrate and is used as energy source in man. It is readily converted to fat which provides a rich store of energy in concentrated form. Glucose is also stored in the liver and muscles as glycogen. When a rapid raise in blood sugar is demanded by the body, glycogen is quickly converted to D-glucose. When the supply of glucose is insufficient, the body mobilises fat stores which are converted to acetate with production of energy by the same oxidative pathways employed in the combustion of glucose. Glucose is also the source of glucuronic acid, with which many foreign substances and their metabolites come to form excretion products. It probably provides the basic substances required for the formation of hyaluronates and chrondroitin sulphates, the supporting structures of the organism.
