Glycogen vs. Polysaccharide

Glycogen and Polysaccharide Definitions
Glycogen
A polysaccharide, (C6H10O5)n, that is the main form of carbohydrate storage in animals and is found 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.
Polysaccharide
Any of a class of carbohydrates, such as starch and cellulose, consisting of a number of monosaccharides joined by glycosidic bonds.
Glycogen
(carbohydrate) A polysaccharide that is the main form of carbohydrate storage in animals; converted to glucose as needed.
Polysaccharide
(carbohydrate) A polymer made of many saccharide units linked by glycosidic bonds.
Cellulose, starches, and complex carbohydrates, such as glycogen, are common polysaccharides in biology.
Glycogen
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.
Polysaccharide
Any of a class of carbohydrates whose molecules contain chains of monosaccharide molecules
