E.g., glucose, fructose, ribose, etc.
Solution 2
Monosaccharides are carbohydrates that cannot be hydrolysed further to give simpler units of polyhydroxy aldehyde or ketone.
Monosaccharides are classified based on the number of carbon atoms and the functional group present in them. Monosaccharides containing an aldehyde group are known as aldoses, and ketoses contain a keto group. Monosaccharides are further classified as trioses, tetroses, pentoses, hexoses, and heptoses according to the number of carbon atoms they contain. For example, a ketose containing three carbon atoms is called ketotriose, and an aldose containing three carbon atoms is called aldotriose.
