What (who) is cellulose - definition

CHEMICAL COMPOUND

Cellulolytic; Cellulolysys; Cellulolysis; E460; Rosette terminal complex; Tunicin; Tunicine; Cellulose ester; Cellulosic; (1,4-beta-D-glucosyl)n; Cellulytic

Cellulose

·adj Consisting of, or containing, cells.

II. Cellulose ·noun The substance which constitutes the essential part of the solid framework of plants, of ordinary wood, linen, paper, ·etc. It is also found to a slight extent in certain animals, as the tunicates. It is a carbohydrate, (C₆H₁₀O₅)_n, isomeric with starch, and is convertible into starches and sugars by the action of heat and acids. When pure, it is a white amorphous mass. ·see Starch, Granulose, Lignin.

cellulose

Cellulose is a substance that exists in the cell walls of plants and is used to make paper, plastic, and various fabrics and fibres.

Wikipedia

Cellulose

Cellulose is an organic compound with the formula (C
₆H
₁₀O
₅)
_n, a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%.

Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton.

Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic micro-organisms that live in their guts, such as Trichonympha. In human nutrition, cellulose is a non-digestible constituent of insoluble dietary fiber, acting as a hydrophilic bulking agent for feces and potentially aiding in defecation.
