Carbohydrate vs. Polysaccharide: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Carbohydrates are organic compounds consisting of carbon, hydrogen, and oxygen, while polysaccharides are complex carbohydrates formed by the linkage of multiple sugar molecules.
Key Differences
Carbohydrates are essential nutrients that include sugars, starches, and fibers, found in fruits, grains, vegetables, and milk products. Polysaccharides are specific types of carbohydrates, comprising long chains of monosaccharide units.

Carbohydrates can be simple (sugars) or complex (starches and fibers). Polysaccharides are complex carbohydrates, specifically long chains of sugars like cellulose, starch, and glycogen.

Digestion of carbohydrates begins in the mouth and is a major source of fuel for the body. Polysaccharides are digested more slowly than simple carbohydrates, providing a gradual release of energy.
