The main structural difference between amylase and cellulose lies in their composition and the way the glucose units are linked together.
1. **Amylase**: This is an enzyme that catalyzes the breakdown of starches into sugars. It does not have a specific structure itself, but it facilitates the hydrolysis of glycosidic bonds in polysaccharides like starch and glycogen. Amylases primarily act on α-1,4-glycosidic bonds found in amylose (a component of starch).
2. **Cellulose**: This is a polysaccharide that serves as a structural component in the cell walls of plants. Cellulose is made up of long chains of β-D-glucose units linked by β-1,4-glycosidic bonds. This difference in linkage contributes to the rigidity and insolubility of cellulose compared to the more soluble nature of starch.
In summary, the structural difference can be summarized as follows:
- **Glycosidic Bonds**: Amylase works with α-1,4-glycosidic bonds (common in starch), while cellulose consists of β-1,4-glycosidic bonds.
- **Functional Role**: Amylase is an enzyme (not a polymer itself), whereas cellulose is a structural polysaccharide.
