NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about carbohydrates is correct?
A
Maltose and lactose are examples of reducing sugars.
B
Sucrose is a reducing sugar because it contains a free aldehyde group.
C
Starch is the main structural polysaccharide found in plants.
D
Polysaccharides are formed by the combination of amino acids.
Correct Answer
Option A
Detailed Explanation
Maltose and lactose are indeed reducing sugars because they have free aldehyde groups, which allow them to reduce other substances. Sucrose is a non-reducing sugar as it does not have a free aldehyde group. Starch serves as a storage polysaccharide, not a structural one, and polysaccharides are formed by monosaccharides, not amino acids.
