Homopolysaccharides are a type of complex carbohydrate composed of only one type of monosaccharide unit. This means that the repeating sugar units within the polymer chain are all identical. Common monosaccharides that form homopolysaccharides include glucose, fructose, and galactose.

The properties and functions of a homopolysaccharide are determined by the specific monosaccharide and the way it is linked together. For instance, starch and glycogen are both homopolysaccharides made of glucose units but differ in their branching patterns and storage locations. Starch serves as the primary energy storage molecule in plants, found in roots, seeds, and grains. Glycogen, on the other hand, is the primary energy storage polysaccharide in animals, stored mainly in the liver and muscles. Cellulose, also a glucose homopolysaccharide, is a structural component of plant cell walls, providing rigidity and support. Its linear chains and beta linkages make it indigestible for most animals.

Chitin is another example, a homopolysaccharide of N-acetylglucosamine, forming the exoskeleton of insects and crustaceans, as well as the cell walls of fungi. The simple repeating unit structure of homopolysaccharides allows for efficient synthesis and storage of energy or provides structural integrity depending on their specific arrangement and linkages.
