Cellulose is a condensation polymer is:

Options

A. Maltose
B. `beta`-Glucose
C. `alpha`-Glucose
D. `beta`-Fructose

Answer

To solve the question "Cellulose is a condensation polymer of:", we will analyze the options provided and understand the structure of cellulose.

### Step-by-Step Solution:

1. **Understanding Cellulose**:
- Cellulose is a polysaccharide that is a major component of the cell wall in plants. It is composed of long chains of glucose units.

2. **Identifying the Type of Linkage**:
- Cellulose is formed by the condensation reaction between glucose units. Specifically, it involves the formation of β-1,4-glycosidic linkages between the glucose molecules.

3. **Identifying the Monomer**:
- The monomer that makes up cellulose is glucose. However, it is specifically the β-glucose form that participates in the formation of cellulose.

4. **Elimination of Small Molecules**:
- During the condensation process, a molecule of water is eliminated when two β-glucose units bond together. This is characteristic of condensation polymers, where small molecules (like water) are released during polymer formation.

5. **Evaluating the Options**:
- The options provided are:
- A) Maltose
- B) Beta-glucose
- C) Alpha-glucose
- D) Beta-fructose
- Since cellulose is formed from β-glucose units, the correct answer is option B, beta-glucose.

### Final Answer:
Cellulose is a condensation polymer of **beta-glucose** (Option B).
