Cellulose (CLL) is a straight chain polymer composed of β-D-glucose units linked by β-1,4-glycoside
bond, which is usually combined with hemicellulose, pectin and lignin, and is the main structural
component of plant cell wall. Cellulose products are widely used in food, paper, plastics, explosives,
electrical engineering and scientific research equipment.
Cellulose can be decomposed into β-D-glucose by heating in acid condition. Under the condition of strong
acid, the content of cellulose is determined with anthrone chromogenic agent.
