Because of the strong hydrogen bonds that occur between cellulose chains, cellulose does not melt or dissolve in common solvents. Thus, it is difficult to convert the short fibers from wood pulp into the continuous filaments needed for artificial silk, an early goal of cellulose chemistry. he existence of cellulose as the common material of plant cell walls was first recognized by Anselm Payen in 1838. It occurs in almost pure form in cotton fiber and in combination with other materials, such as lignin and hemicelluloses, in wood, plant leaves and stalks, etc.
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%.ellulose 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.
