Aldehydes and ketones play an important role in the chemistry of carbohydrates. The term carbohydrate literally means a "hydrate" of carbon, and was introduced to describe a family of compounds with the empirical formula CH2O. Glucose and fructose, for example, are carbohydrates with the formula C6H12O6. These sugars differ in the location of the C=O double bond on the six-carbon chain, as shown in the figure below. Glucose is an aldehyde; fructose is a ketone.
