Cellulose \Cel"lu*lose`\, n. (Chem.) The substance which constitutes the essential part of the solid framework of plants, of ordinary wood, cotton, 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.

1840, from French cellulose, coined c.1835 by French chemist Anselme Payen (1795-1871) and confirmed 1839, from noun use of adjective cellulose "consisting of cells," 18c., from Latin cellula (see cellulite) + -ose (see -ose (2)).


a. Consisting of, or containing, cells. n. 1 A complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products, such as paper, textiles, pharmaceuticals, and explosives. 2 (context organic compound English) A polysaccharide containing many glucose units in parallel chains.


n. a polysaccharide that is the chief constituent of all plant tissues and fibers


Cellulose is an organic compound with the formula , 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%.
