Cellulose in contrast has quite a distinct function as the principal structural component of the plant cell wall. Cellulose is also composed entirely of glucose molecules which are in the beta linkage and cellulose is unbranched (Fig. 5) . This β (1-4) linkage causes cellulose to form long extended chains that pack side by side to form fibers of great mechanical strength. Starch is the chief form of fuel storage in most plants, whereas cellulose is the main extracellular structural component of the

Unformatted text preview: rigid cell walls and the fibrous and woody tissues of plants. Glycogen , which resembles starch in structure, is the chief storage carbohydrate in animals. In addition, some polysaccharides and shorter polymers of sugars act as markers for a variety of cell recognition processes, including the adhesion of cells to their neighboring cells and the transport of proteins to appropriate intracellular locations....
