Question

Which is not a polysaccharide? Choose the correct answer from the options given below:

• A. Pectin
• B. Lignin
• C. Hemicellulose
• D. Glucose

Hint:

Glucose is a monosaccharide (single sugar unit), not a long-chain polysaccharide!

Answer 1

The Correct Option is D

Polysaccharides are complex carbohydrates made from long chains of monosaccharide units. Glucose is a simple sugar (monosaccharide), not a polysaccharide. Pectin, hemicellulose, and even though lignin is not a carbohydrate, it’s often found associated with polysaccharides in plants—yet glucose clearly stands out as not a polysaccharide.
