car·bo·hy·drates (CHO),

Class name for the aldehydic or ketonic derivatives of polyhydric alcohols, the name being derived from the fact that the most common monomeric examples of such compounds have formulas that may be written as Cn(H2O)n (for example, glucose, C6(H2O)6); although they are not true hydrates and the name is, in that sense, a misnomer. The group includes compounds with relatively small molecules, such as the simple sugars (monosaccharides, disaccharides, etc.), as well as macromolecular (polymeric) substances such as starch, glycogen, and cellulose. The carbohydrates most typical of the class contain carbon, hydrogen, and oxygen only, but carbohydrate metabolic intermediates in tissues also contain phosphorus. See: saccharide.

(CHO) (kahr'bō-hī'drāts)
Class name for the aldehydic or ketonic derivatives of polyhydric alcohols. Most such compounds have formulas that may be written Cn(H2O)n, although they are not true hydrates. The group includes simple sugars (monosaccharides, disaccharides), as well as macromolecular (polymeric) substances such as starch, glycogen, and cellulose polysaccharides.
See also: saccharides


Compounds of carbon, oxygen and hydrogen forming an important part of the diet and contributing mainly energy. They include sugars, starches and celluloses and are structurally classified into three groups—monosaccharides, disaccharides and polysaccharides. Starches and celluloses are polysaccharides.


Compounds, such as cellulose, sugar, and starch, that contain only carbon, hydrogen, and oxygen, and are a major part of the diets of people and other animals.
Mentioned in: Laxatives


saccharides Cn(H2O)n, e.g. glucose C6(H2O)6, sucrose C12(H2O)12; some are simple molecules (e.g. monosaccharides), others form complex macromolecules (e.g. glycogen)


(CHO) (kahr-bō-hī'drāts)
Compound that includes simple sugars and macromolecular (polymeric) substances (e.g., starch, glycogen).

carbohydrates, a group of organic compounds with the class name saccharides, which are the aldehydric or ketonic derivatives of polyhydric alcohols. Ones such as sugar, starch, cellulose, and gum are generally synthesized by green plants. They constitute the main energy source in the diet and are classified as mono-, di-, tri-, and polysaccharides.
