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 Î²(1â4) 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 40â50% and that of dried hemp is approximately 45%. Cellulose is mainly used to produce paperboard and paper.ellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.

Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH 2 -COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone.arboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH 2 -COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone.
