Cellular is a linear and unbranched homopolysaccharide of glucose wherein the glucose residues are bonded together by beta 1-4 glycosidic linkage. It is a homopolysaccharide since it is a polymer of a single type of monomer, which is the glucose residue.
The long parallel chains of cellulose are crisscrossed by hydrogen bonds. Cellular is a tough and water-insoluble substance that forms a rigid protective covering around the cells of plants.
