Introduction:

Carbohydrates are the most abundant biomolecule present in the Earth. Based on the number of sugar units they are classified as monosaccharide, disaccharide, oligosaccharide, or polysaccharide. Monosaccharides are the simplest carbohydrate unit. They cannot be hydrolyzed further. When a monosaccharide contains an aldehyde as its functional group, it iscalledaldose. The presence of ketones as its functional group shows that it is ketoses.

Expert Solution & Answer

Explanation of Solution

The simplest carbohydrate, monosaccharide can either be aldoses or ketoses based on its functional group. When the functional group is an aldehyde, it is called an aldose. It is a ketose when the functional group is a ketone. The class, to which the given molecules belong, is described below:
