Polysaccharides are complex carbohydrates composed of long chains of monosaccharide units linked together by glycosidic bonds. These large molecules are fundamental to life, playing crucial roles in energy storage and structural support in both plants and animals. Common monosaccharide units include glucose, fructose, and galactose. The specific type of monosaccharide, the length of the chain, and the types of glycosidic linkages determine the physical and chemical properties of the polysaccharide.

In plants, starch serves as a primary energy storage molecule. It is composed of glucose units arranged in linear (amylose) and branched (amylopectin) chains. Cellulose, also derived from glucose, is a major structural component of plant cell walls, providing rigidity and support. Its linear structure and strong hydrogen bonding between chains contribute to its strength.

In animals, glycogen acts as the main storage form of glucose, primarily in the liver and muscles. Glycogen is structurally similar to amylopectin but has more frequent branching, allowing for rapid release of glucose when energy is needed. Chitin, another important polysaccharide, is found in the exoskeletons of arthropods and the cell walls of fungi, providing structural integrity. Unlike starch and cellulose, chitin contains nitrogen in its repeating unit. Polysaccharides are vital for a wide range of biological functions and are a key area of study in biochemistry and nutrition.
