Amylopectin vs. Glycogen: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on November 27, 2023
Amylopectin is a branched polysaccharide of plants, while glycogen is the main storage polysaccharide in animals.

Key Differences

Amylopectin and glycogen are both polysaccharides, but they are found in different organisms. Amylopectin is one of the two components of starch, primarily found in plants, and plays a significant role in energy storage. On the other hand, glycogen, sometimes referred to as "animal starch," is stored mainly in the liver and muscles of animals, supplying them with a quick source of energy.

Amylopectin has a slightly less branched structure compared to glycogen. This means that while both molecules store glucose units, the way they branch and organize these units varies. Glycogen's more frequent branching allows for rapid glucose release, suitable for the quick energy needs of animals.

In terms of solubility and structure, amylopectin's branching is at intervals of 20-30 glucose units, which contributes to its semi-crystalline nature in starch granules. Glycogen, with its more frequent branching every 8-12 glucose units, is highly soluble and doesn't form a crystalline structure like amylopectin.

To sum it up, while both amylopectin and glycogen serve as energy storage molecules, they differ in their structure, branching frequency, and the organisms they are found in. Amylopectin is a primary component in plant starch, whereas glycogen is predominant in animals.

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.

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.
