Concept Introduction:

Simplest carbohydrates are known as monosaccharides.  They contain three to six carbons generally in a chain form with a carbonyl group present in the terminal or the adjacent carbon atom from the terminal.  Monosaccharides that have the carbonyl group at the terminal carbon atom C1 are known as aldoses and the monosaccharides that have the carbonyl group on the adjacent carbon atom C2 are known as ketoses.

Carbohydrates undergo reduction similar to an alkene.  When an aldose is treated with hydrogen in presence of palladium as catalyst the carbonyl group present in the aldose is reduced resulting in formation of alditol.  This is also known as “sugar alcohol”.

Carbohydrates also undergo oxidation.  Monosaccharides that are aldoses contains an aldehyde group.  The carbonyl of the aldehyde undergoes oxidation very easily resulting in the formation of carboxyl group.  The product formed is known as aldonic acid.
