  • Interesting fact: Alfred Nobel used a cellulose adhesive (nitrocellulose) as the chemical binder for nitroglycerin, which he used in his invention of dynamite.
    • a Cellulose Consisting of, or containing, cells.
    • n Cellulose (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. "Unsized, well bleached linen paper is merely pure cellulose ."

  • Interesting fact: Cellophane is not made of plastic. It is made from a plant fiber, cellulose, which has been shredded and aged.
    • cellulose Containing cells.
    • n cellulose In botany, the essential constituent of the primary wall-membrane of all cells, a secretion from the contained protoplasm, isomerous with starch in its composition, and allied to starch, sugar, and inulin. It rarely or never exists in a simple condition unmixed with coloring or mineral matters, etc.; and with age it becomes largely transformed into lignin, suberin, or mucilage. Cotton and the bleached fiber of flax and hemp are nearly pure cellulose, and in some filter-paper it is almost chemically pure. Cellulose is remarkable for its insolubility, being dissolved without change only by an ammoniacal solution of oxid of copper, from which it may be again precipitated. Under the action of concentrated or boiling acids, or of caustic alkalis, many different products are obtained, according to the method of treatment. It is changed to glucose by long boiling with dilute sulphuric or hydrochloric acid; a substance resembling parchment is obtained by treating unsized paper with cold sulphuric acid; strong nitric acid, or a mixture of nitric and sulphuric acids, converts forms of cellulose into guncotton, etc. In its unchanged condition it is not colored by iodine except usually with a faint yellowish tint, which becomes a bright blue on the addition of strong sulphuric acid. Cellulose is also said to exist in the tunics of Ascidia and in other invertebrates.
    • cellulose Formed of cellulose.
    • n cellulose A light material used as a packing in coffer-dam compartments of warships in the vicinity of the water-line. In the United States navy, cellulose from the husk of the cocoanut and that from the pith of cornstalks have been used for this purpose. See coffer-dam, 3.

The cellulose is the same in all types of biomass, except for the degree of polymerisation (i.e. the number of monomer units per polymer).

Cellulose is an extraordinarily stable polysaccharide due to its structure: insoluble, relatively resistant to acid and base hydrolysis, and inaccessible to all hydrolytic enzymes except those from a few biological sources.

Cellulose is the most widely studied substance in the field of wood and biomass combustion; by comparison, few studies have been carried out on the combustion of hemicelluloses or lignin (di Blasi, 1998), due perhaps to the relative thermal instability of these compounds.
