Linkage present in between glucose residues of cellulose is

Options

A. `beta1to4`
B. `beta1to6`
C. `alpha1to4`
D. `alpha1to6`.

Answer

To determine the type of linkage present between glucose residues in cellulose, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Cellulose**:
- Cellulose is a polysaccharide composed of long chains of glucose units. It is a major component of the plant cell wall.

2. **Identify the Types of Linkages**:
- There are different types of glycosidic linkages that can occur between glucose molecules, specifically:
- Alpha (α) linkages
- Beta (β) linkages
- The numbers associated with these linkages (1, 4 or 1, 6) indicate the carbon atoms involved in the linkage.

3. **Focus on the Linkage in Cellulose**:
- In cellulose, the glucose units are linked together by β (beta) glycosidic bonds.
- Specifically, the linkage is β-1,4, meaning that the first carbon of one glucose is linked to the fourth carbon of the next glucose unit.

4. **Eliminate Incorrect Options**:
- The other options provided are:
- β-1,6
- α-1,4
- α-1,6
- Since cellulose is known to have β-1,4 linkages, these options can be ruled out.

5. **Conclude the Correct Answer**:
- Therefore, the correct linkage present between glucose residues in cellulose is **β-1,4 linkage**.

### Final Answer:
The linkage present between glucose residues of cellulose is **β-1,4 linkage**.
