Extended data:
Cellulose is the main component of plant cell wall, which supports and protects plants. Cellulose can not be directly digested and utilized by ordinary animals, but can be digested and decomposed by some microorganisms. It has no nutritional value for human beings, but it has the physiological function of stimulating intestinal peristalsis, so it is an indispensable component in the diet.
Cellulose is the main raw material for manufacturing contracts and cotton spinning. Rayon and rayon can be made by processing. For example, alkali can partially dissolve cotton cellulose to form alkali cellulose, and then treat it with carbon disulfide to obtain water-soluble yellow cellulose-rayon raw material.
Cellulose acetate, combined with acetic acid, is the raw material of photographic film, rayon and various plastics. Nitrocellulose is formed from cellulose treated with concentrated nitric acid, which is the raw material for making explosives.
