Question

Which of the following statement is not true for Ketose?

• A. It has 3 - 7 carbons
• B. It is a simple sugar
• C. Ketoses are nonreducing sugars because they do not contain aldehyde group
• D. All of the above

Answer 1

The correct option is C

Ketoses are nonreducing sugars because they do not contain aldehyde group

Ketoses are simple sugars, that can be formed from 3 upto 7 carbons. All monosaccharides are reducing sugars, because the aldoses contain the aldehyde group that can easily be oxidised to acid, and the ketoses can tautomerize in solution to form the aldehyde group.
