Question

Ketose sugar is

• A. Galactose
• B. Fructose
• C. Mannose
• D. Glucose

Hint:

Fructose is the most common naturally occurring ketose sugar.

Answer 1

The Correct Option is B

Step 1: Monosaccharides are classified as aldoses or ketoses based on the functional group present.
Step 2: Ketose sugars contain a ketone group, while aldose sugars contain an aldehyde group.
Step 3: Fructose contains a ketone functional group and is therefore a ketose sugar.
Step 4: Galactose, mannose, and glucose are aldose sugars. Hence, fructose is the correct answer.
