Cellulose is a polymer of

Options

A. glucose
B. fructose
C. ribose
D. sucrose

Answer

**Step-by-Step Solution:**

1. **Understanding Cellulose**: Cellulose is a type of carbohydrate known as a polysaccharide. It is a complex molecule made up of many repeating units.

2. **Identifying the Monomer**: The repeating unit or monomer of cellulose is D-glucose. This means that cellulose is made up of multiple D-glucose molecules linked together.

3. **Linkage Type**: The D-glucose units in cellulose are connected by a specific type of bond known as a glycosidic linkage. In the case of cellulose, these linkages are beta glycosidic linkages.

4. **Linkage Position**: The beta glycosidic linkages occur between the C1 carbon of one D-glucose molecule and the C4 carbon of the next D-glucose molecule. This specific arrangement is crucial for the structural properties of cellulose.

5. **Conclusion**: Since cellulose is composed of D-glucose units linked together, we can conclude that cellulose is a polymer of glucose.

**Final Answer**: Cellulose is a polymer of glucose.
