Hemicellulose is a complex carbohydrate found in the cell walls of plants, playing a crucial role in their structure and strength. Unlike cellulose, which is rigid and tough, hemicellulose is more flexible and helps bind with other components like cellulose and lignin. This flexibility allows plants to maintain their shape while also being able to grow and expand. In addition to its structural role, hemicellulose is important for various industrial applications. It can be extracted from plant materials and used in products like biofuels, paper, and food additives. Its versatility makes it a valuable resource in both environmental and commercial contexts.
