from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun A polysaccharide, (C6H10O5)n, that is the main form of carbohydrate storage in animals and occurs primarily in the liver and muscle tissue. It is readily converted to glucose as needed by the body to satisfy its energy needs.

from The Century Dictionary.

  • noun A substance, C6H10O5, belonging to the carbohydrates.
  • noun In mycology, same as epiplasm.

  • noun (Physiol. Chem.) A white, amorphous, tasteless substance resembling starch, soluble in water to an opalescent fluid. It is found abundantly in the liver of most animals, and in small quantity in other organs and tissues, particularly in the embryo. It is quickly changed into sugar when boiled with dilute sulphuric or hydrochloric acid, and also by the action of amylolytic ferments.

  • These results had several important ramifications: they explained the course of heat production measured by Hill; and they confirmed and extended a famous theory of Pasteur's that less glycogen is consumed in muscle metabolism in the presence of oxygen than in its absence.

  • Once you use up all of your available glucose during the digestive phase of metabolism (your body stores only about 300 calories in the short-term glycogen reservoir), it taps a long-term reservoir: fatty tissue in the form of triglycerides (molecules that include a carbohydrate-containing glycerol).

  • Hence glycogen is converted to glucose which can enter the blood stream.

  • Further work showed that uridine diphosphate glucose is involved in glycogen synthesis and adenosine diphosphate glucose in that of starch.

  • Later it was shown, in collaboration with Collip, that other symptoms of diabetes, namely the ketonuria and the absence of glycogen from the liver, were favourably influenced by the extracts and, with Hepburn, that the respiratory quotient became raised.

  • The same process may, however, also proceed in the opposite direction, so that glycogen is formed from the Cori ester.
