Under strongly acidic conditions aldoses become oxidised to dicarboxylic acids called aldaric acids
<h3>
What are aldaric acids?</h3>
The formula for aldaric acids is HOOC-(CHOH)n-COOH, and they are a kind of sugar acids in which the sugars' terminal hydroxyl and carbonyl groups have been substituted by terminal carboxylic acids.
Aldoses are often oxidised with nitric acid to produce aldaric acids. The open-chain (polyhydroxyaldehyde) form of the sugar interacts in this reaction.
Aldoses that have both the hydroxyl function of the terminal carbon and the aldehyde function of the first carbon completely oxidised to carboxylic acid functions are referred to as aldaric acids. (Aldonic acid is produced by oxidising just the aldehyde, whereas uronic acid is produced by oxidising only the terminal hydroxyl group.) Like unoxidized sugars, aldaric acids cannot produce cyclic hemiacetals, but they occasionally can form lactose.
