What are monosaccharides?

Text Solution

Verified by Experts

Monosaccharides are simple carbohydrates which can not be hydrolysed to still simpler carbohydrates. Usually they have the general formula `(CH_(2)O)_(n)`, where n = 3-7. These are of two types: aldoses (Which contain an aldehyde group) and ketoses (which contain a keto group). Thus, glucose `(C_(6)H_(12)O_(6))` is an aldose while fructose `(C_(6)H_(12)O_(6))` is a ketose.
