Carbohydrates: The Monosaccharides. The term carbohydrate was originally used to describe compounds that were literally hydrates of carbon because they had the empirical formula CH 2 O. In recent years, carbohydrates have been classified on the basis of their structures, not their formulas.
The name carbohydrate reveals the chemical make up of this nutrient class. Indeed, carbo means carbon, while hydrate means water, a combination of hydrogen and oxygen molecules. All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.
