Natural polysaccharides are large molecules made up of long chains of sugar units, known as monosaccharides. They are found in various plants and animals and serve essential functions, such as energy storage and structural support. Common examples include starch, cellulose, and glycogen. These polysaccharides are important in many industries, including food, pharmaceuticals, and cosmetics. They can act as thickeners, stabilizers, or gelling agents. Additionally, natural polysaccharides are often used in dietary supplements due to their health benefits, such as promoting digestive health and providing dietary fiber.
