Oligosaccharides vs. Polysaccharides: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 27, 2023
Oligosaccharides are carbohydrates with a few sugar units, while polysaccharides are long chains of numerous sugar units.

Key Differences

Oligosaccharides consist of a small number (typically 3-10) of sugar molecules linked together. Polysaccharides, in contrast, are larger molecules made up of many sugar units, ranging from a few hundred to thousands.

Oligosaccharides often function in cell recognition and are found in small quantities in foods. Polysaccharides serve as energy storage (like starch) or structural components (like cellulose) in plants and animals.
