Explanation:
Detailed explanation-1: -The term carbohydrates (or sugars) refers to a group of polyhydroxy aldehydes or ketones. This means that a carbohydrate molecule contains several hydroxyl groups and either an aldehyde or a ketone group (see below).
Detailed explanation-2: -An aldose is defined as a monosaccharide whose carbon skeleton has an aldehyde group. They are primarily found in plants. Ketose is a monosaccharide whose carbon skeleton has a ketone group. Only in the presence of reducing sugar, they can isomerize to aldose.
Detailed explanation-3: -Monosaccharides are good examples of polyhydroxy aldehydes. These are simple sugars and they act as the building blocks of carbohydrates such as disaccharides and polysaccharides.
