Glycogen vs. Polysaccharide: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Updated on November 22, 2023
Glycogen is a complex carbohydrate stored in animals for energy. Polysaccharide is a carbohydrate molecule consisting of long chains of monosaccharide units.

Key Differences

Glycogen is a specific type of polysaccharide that serves as the primary storage form of glucose in animals and fungi. Polysaccharides, in general, are carbohydrates formed from long chains of monosaccharides.

Glycogen is characterized by its structure, which is highly branched and compact, allowing for rapid mobilization of glucose. Polysaccharides can have varying structures, from linear to highly branched, and include substances like cellulose and starch.

In glycogen, the glucose units are linked by α(1→4) glycosidic bonds, with branches formed by α(1→6) bonds. Polysaccharides can have different types of glycosidic bonds, influencing their structure and function.

Glycogen is synthesized and stored mainly in the liver and muscle tissues in humans. Polysaccharides, depending on their type, are found in a wide variety of biological contexts, including plant cell walls (cellulose) and food reserves in plants (starch).

The primary role of glycogen is to provide a readily available source of energy during periods of high demand. Polysaccharides, while also often serving as energy sources, have diverse functions, including structural support in plants and invertebrates.

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.
