Q.34 Monosaccharides contain carbonyl group hence are classified, as aldose or ketose. The number of carbon atoms present in the monosaccharide molecule is also considered for classification. In which class of monosaccharide will you place fructose?


Monosaccharides contain carbonyl groups.

Hence, are classified as aldose or ketose.

When the aldehyde group is present, the monosaccharides are known as aldose.

When the ketone group is present, the monosaccharides are known as a ketose. Fructose has a molecular formula C6H12O6 Containing 6 carbon and Keto grOup and is Classified as Ketohexose.
