Cellulose is a linear polysaccharide that serves as the primary structural component of the cell walls of most plants. Chemically, it is a polymer composed of D-glucose units linked together by $\beta$-1,4 glycosidic bonds. This specific molecular arrangement gives cellulose considerable tensile strength, making it an essential biological material for plant structural support. Due to the extensive hydrogen bonding between adjacent chains, crystalline microfibrils form, which provide rigidity and resistance to biological degradation in most animals. In industrial and scientific contexts, cellulose and its derivatives are highly valued for applications in textiles, biomaterials, and the development of biofuels, where the polysaccharide structure can be broken down into simpler fermentable sugars.
