Detailed explanation-1: -Monosaccharides are carbohydrate molecules that cannot be broken down by hydrolysis2 into simpler (smaller) carbohydrate molecules. Hence, monosaccharides are at times referred to as “simple sugars” or just :sugars, ‘’ which infers that they are the simplest (smallest) of the carbohydrates.

Detailed explanation-2: -Monosaccharides may also be classified based on the type of carbonyl group they contain: (1) Aldose, -CHO (aldehyde) and (2) Ketose, C=O. (ketone). An aldose is a monosaccharide that contains an aldehyde group (-CHO) whereas a ketose is one that contains a ketone (C=O).

Detailed explanation-3: -monosaccharide, also called simple sugar, any of the basic compounds that serve as the building blocks of carbohydrates.
