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.
In food science and in many informal contexts, the term carbohydrate often means any food that is particularly rich in the complex carbohydrate starch (such as cereals, bread and pasta) or simple carbohydrates, such as sugar (found in candy, jams, and desserts).ormerly the name carbohydrate was used in chemistry for any compound with the formula C m (H 2 O) n. Following this definition, some chemists considered formaldehyde (CH 2 O) to be the simplest carbohydrate, while others claimed that title for glycolaldehyde.
