Definition
Polysaccharides are large, complex carbohydrates composed of long chains of monosaccharide units, which serve various functions in living organisms; examples include starch, a storage form of energy in plants, glycogen, a storage form of energy in animals, and cellulose, a structural component of plant cell walls.
Summary
Polysaccharides are essential carbohydrates made up of long chains of sugar units. They play critical roles in energy storage, such as starch in plants and glycogen in animals, and provide structural support, particularly cellulose in plant cell walls. Understanding polysaccharides is vital for grasping how living organisms store energy and maintain their structure. In addition to their biological functions, polysaccharides have significant applications in various industries, including food, pharmaceuticals, and biofuels. Their diverse roles highlight their importance in both health and industry, making them a key topic in the study of biology and nutrition.
