Branched chain structure is shown by

Options

A. Amylopectin
B. Cellulose
C. Amylose
D. Nylon

Answer

To determine which biomolecule exhibits a branched chain structure, we will analyze the options provided in the context of their structural characteristics.

### Step-by-Step Solution:

1. **Identify the Options**: The question mentions amylopectin, cellulose, amylose, and nylon. We need to evaluate each of these to see if they exhibit a branched chain structure.

2. **Understanding Amylose**:
- Amylose is a component of starch.
- It has a straight chain structure composed of D-glucose units linked by α(1→4) glycosidic bonds.
- Therefore, amylose does not have a branched structure.

3. **Understanding Amylopectin**:
- Amylopectin is also a component of starch.
- It has a branched structure due to the presence of α(1→4) glycosidic bonds for the straight chains and α(1→6) glycosidic bonds at the branching points.
- This means that amylopectin does exhibit a branched chain structure.

4. **Understanding Cellulose**:
- Cellulose is a polysaccharide made up of β(1→4) linked D-glucose units.
- It forms a straight chain structure and does not have branches.
- Thus, cellulose is not a branched structure.

5. **Understanding Nylon**:
- Nylon is a synthetic polymer.
- It is formed through the condensation of diamines and dicarboxylic acids, resulting in a linear structure.
- Therefore, nylon does not exhibit branching.

6. **Conclusion**:
- Among the options provided, only amylopectin shows a branched chain structure.

### Final Answer:
The branched chain structure is shown by **amylopectin**.
