Question

Macromolecule chitin is ?

• A. Simple polysaccharide
• B. Sulphur containing polysaccharide
• C. Phosphorus containing polysaccharide
• D. Nitrogen containing polysaccharide

Answer 1

The correct option is D

Nitrogen containing polysaccharide

The correct option is D.

Explanation of correct option:

1. Chitin is the most abundant amino polysaccharide polymer found in nature, and it is the building material that gives crustaceans, insects, and fungi their exoskeletons and cell walls their strength.
2. Chitin is a nitrogen-containing modified polysaccharide made up of units of N-acetyl-D-glucosamine (more precisely, 2-(acetylamino)-2-deoxy-D-glucose).

Explanation of incorrect option:

Option A

Chitin is not a simple polysaccharide.

Option B

Chitin is not a Sulphur containing polysaccharide.

Option C

Chitin is not a Phosphorus-containing polysaccharide.

Final answer: Macromolecule chitin is a nitrogen-containing polysaccharide
