- n. 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. Also called animal starch.
Century Dictionary and Cyclopedia
- n. A substance, C6H10O5, belonging to the carbohydrates. When pure it is a white, amorphous, tasteless powder, insoluble in alcohol, soluble in water, and converted by boiling with acids into dextrose. Diastase converts it into dextrine, maltose, and dextrose. Iodine gives it a reddish-brown color. Glycogen is found in many animal tissues, both of vertebrates and invertebrates, as well as in certain fungi. It is especially abundant in the liver. It is largely if not wholly derived from the carbohydrates of the food, and appears to be a reserve material deposited in the liver, which is converted as required into sugar and so enters the circulation. Also called
animal starch . - n. In mycology, same as epiplasm.
Wiktionary
- n. biochemistry A polysaccharide that is the main form of carbohydrate storage in animals; converted to glucose as needed.
GNU Webster's 1913
- n. (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.
WordNet 3.0
- n. one form in which body fuel is stored; stored primarily in the liver and broken down into glucose when needed by the body
Examples
“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.”
Otto Meyerhof and the Physiology Institute: the Birth of Modern Biochemistry
“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).”
“They are fueled by a small store of a carbohydrate called glycogen, which is already in the fibers, and is rapidly converted into energy by enzymes right in the cell fluids.”
Simon & Schuster: On Food and Cooking, The Science and Lore of the Kitchen
“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.”
“They observed that the marked decrease in glycogen and lowering of blood sugar in hypophysectomized rats occurred with a concomitant increase in the rate of glucose oxidation.”
“The human body contains a small amount of a substance called glycogen, which is an animal starch or sugar.”
“Now, Li-Huei Tsai, the Picower Professor of Neuroscience in MIT's Department of Brain and Cognitive Sciences, and colleagues have shown for the first time that DISC1 directly inhibits the activity of a brain enzyme called glycogen synthase kinase 3 beta, also known as GSK3B.”
