monosaccharides whether aldose or ketose are reducing sugars Monosaccharides are further classified on the basis of number of carbon
atoms and the functional group present in them If a monosaccharide
contains an aldehyde group, it is known as an aldose and if it contains
a keto group, it is known as a ketose
