Question

Chemically, chitin is:

• A. Nitrogenous polysaccharide
• B. Halogenated polysaccharide
• C. Polypeptide
• D. Saturated fatty acid

Hint:

Chitin:
- Nitrogenous polysaccharide.
- Polymer of N-acetylglucosamine.
- Found in insect exoskeleton and fungal cell walls.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of chitin, a structural component of insects and fungi.

Step 2: Detailed Explanation:
Chitin is a nitrogenous polysaccharide.
It is a polymer of N-acetylglucosamine (a derivative of glucose).
It contains nitrogen in the form of acetyl groups.
Halogenated polysaccharide (B): Not correct.
Polypeptide (C): Protein.
Saturated fatty acid (D): Lipid.
Thus, chitin is a nitrogenous polysaccharide.

Step 3: Final Answer:
Thus, chemically, chitin is a nitrogenous polysaccharide, which corresponds to option (A).
