The word carbohydrate was originally derived from the fact that the greater part of the compounds in this class had the empirical formula C n (H2O) n . The values of n ranged from three to many thousands. This formula is now considered too restrictive, and a more useful definition might be “polyhydroxy aldehydes or ketones and their derivatives.” This latter definition encompasses deoxy sugars, sugar alcohols, sugar acids, and amino sugars.
