aldoses
An aldose is a monosaccharide (a simple sugar) with a carbon backbone chain with a carbonyl group on the endmost carbon atom, making it an aldehyde, and hydroxyl groups connected to all the other carbon atoms.
and ketoses are reducing sugars. Stronger oxidizing agents can oxidize other hydroxyl groups of aldoses. For example, dilute nitric acid oxidizes both the aldehyde group and the primary alcohol of aldoses to give aldaric acids.
Are ketoses reducing?
All monosaccharide ketoses are reducing sugars, because they can tautomerize into aldoses via an enediol intermediate, and the resulting aldehyde group can be oxidised, for example in the Tollens' test or Benedict's test.
Are ketoses reducing sugars MCAT?
Both aldoses and ketoses are considered to be reducing sugars.
