Chapter Two: Carbohydrates-The Polysaccharides
Cellulose

Cellulose and amylose are both based on glucose. Cellulose is the main structural component of plants. The leaves, stems and roots of all plants are made of cellulose. It is indigestable to most animals and has little nutritional value.
Amylose

Amylose is starch. Plants frequently store their energy reserves as starch. Potatos for example are made mostly of starch. The major differences between the characteristics of these two molecules lies in how the glucose molecules are linked together. As you can see the starch molecules loop around while the cellulose molecules lie very close together. These differences in their structure account for the differences in their behavior
