Cellulose is a complex carbohydrate and the main structural component of the primary cell wall of green plants, algae, and oomycetes. It is an organic polymer consisting of a linear chain of several hundred to many thousands of beta acetal linked glucose units. Cellulose is a vital structural material in plants, providing rigidity and strength. It is also the most abundant organic polymer on Earth, making up a significant portion of biomass. Humans and most animals cannot digest cellulose due to the lack of the necessary enzyme, cellulase, to break its beta acetal linkages. However, some microorganisms possess this enzyme, enabling them to break down cellulose. This breakdown process is crucial for nutrient cycling in ecosystems.

Industrially, cellulose is a versatile material. It is the primary raw material for paper production. Various forms of processed cellulose, such as cellulose acetate and nitrocellulose, have found applications in the manufacturing of textiles (rayon), plastics, films, explosives, and lacquers. Its biodegradable nature and renewable source make it an attractive alternative to petroleum-based materials in certain applications, though its processing can be energy-intensive. The study of cellulose and its derivatives continues to explore new uses in areas like sustainable packaging and advanced biomaterials.
