glycogen /gly·co·gen/ (gli´ko-jen) a highly branched polysaccharide of glucose chains, the chief carbohydrate storage material in animals, stored primarily in liver and muscle; it is synthesized and degraded for energy as demanded.glycogen´ic

glycogen
gly·co·gen (gl  k -jn)n. A polysaccharide that is the main form of carbohydrate storage in animals and occurs mainly in liver and muscle tissue; it is readily converted to glucose. Also called animal starch. gly  co·genic (-j n k) adj. |
Glycogen
A macromolecule composed mainly of glucose that serves as the storage form of glucose that is not immediately needed by the body.
Mentioned in: Glycogen Storage Diseases
glycogen
[glī′kəjən]
Etymology: Gk, glykys, sweet, genein, to produce
a polysaccharide that is the major carbohydrate stored in animal cells. It is formed from repeating units of glucose and stored chiefly in the liver and, to a lesser extent, in muscle cells. Glycogen is depolymerized to glucose, which is released into the circulation as needed by the body. Also called animal starch, hepatin, tissue dextrin. See also glucose.
glycogen (glī´kōjen),
n a branched, homopolysaccharide of glucose held by α 1-4 and α 1-6 glucosidic bonds. Liver glycogen provides a ready source of blood glucose through glycogenolysis.
glycogen storage disease,
n a group of inherited disorders of glycogen metabolism. An enzyme deficiency causes glycogen to accumulate in abnormally large amounts in various parts of the body. The full taxonomy runs from Type I to Type VII.
glycogen
a polysaccharide, the chief carbohydrate storage material in animals. It is formed and stored in the liver and muscles (phosphorylytically cleaved to glucose-1-phosphate). Called also animal starch.
glycogen granules
electron-dense accumulation of glycogen molecules.
glycogen nephrosis
deposition of glycogen in the renal tubules in diabetes mellitus but without apparent effect on renal function.
glycogen phosphorylase
glycogen phosphorylase the major enzyme in glycogenolysis, leading to the release of glucose-1-phosphate from glycogen. This enzyme is activated by phosphorylation from ATP by glycogen phosphorylase kinase, activated by cAMP-dependent protein kinase or by Ca2+ via calmodulin, or inhibited by hydrolysis of the phosphate by glycogen phosphorylase phosphatase.
glycogen synthase
an enzyme in the glycogenesis process.
glycogen
Animal starch A polysaccharide of glucose-produced primarily in the liver and skeletal muscle, which is analogous to plant starch, but contains more highly branched chains of glucose subunits
