Definition & Meaning of "polysaccharide"

What is "polysaccharide"?

Polysaccharides are complex carbohydrates made up of multiple sugar molecules linked together. They serve as a major source of energy and play important structural roles in living organisms. Common examples of polysaccharides include starch, glycogen, and cellulose. Starch, found in foods like potatoes, rice, and bread, serves as a storage form of energy in plants and is a major source of carbohydrates in the human diet. Glycogen, stored in the liver and muscles, serves as a short-term energy reserve in animals and humans. Cellulose, found in plant cell walls, provides structural support and dietary fiber, aiding in digestion. Polysaccharides are important for providing energy, supporting cellular structure, and maintaining overall health.
