Chitin is polymer of

Options

A. N-acetyl muramic acid
B. N- acetyl gluconic acid
C. N-acetyl glucosamine
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Chitin**: Chitin is a biopolymer that is primarily found in the cell walls of fungi and the exoskeletons of arthropods, such as insects and crustaceans.

2. **Identifying the Monomer**: To determine what chitin is a polymer of, we need to look at the options provided:
- N-acetyl muramic acid
- N-acetyl gluconic acid
- N-acetyl glucosamine
- None of the above

3. **Analyzing the Options**:
- N-acetyl muramic acid is not a component of chitin.
- N-acetyl gluconic acid is also not related to chitin.
- N-acetyl glucosamine, however, is the correct monomer that makes up chitin.

4. **Conclusion**: Chitin is a polymer of N-acetyl glucosamine. Therefore, the correct answer is option number 3: N-acetyl glucosamine.

**Final Answer**: Chitin is a polymer of N-acetyl glucosamine.
