any of a large group of organic compounds, including sugars, such as sucrose, and polysaccharides, such as cellulose, glycogen, and starch, that contain carbon, hydrogen, and oxygen, with the general formula Cm(H2O)n: an important source of food and energy for animals Informal term carb

1851, from carbo-, comb. form of carbon, + hydrate (n.), denoting compound produced when certain substances combine with water, from Greek hydor “water” (see water (n.1)).

The name carbohydrate was given to these compounds because, in composition, they are apparently hydrates of carbon. In structure, however, they are far more complex. [Flood]

carbohydrate car·bo·hy·drate (kär’bō-hī’drāt’)
Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals; they are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio 1:2:1.
Any of a large class of organic compounds consisting of carbon, hydrogen, and oxygen, usually with twice as many hydrogen atoms as carbon or oxygen atoms. Carbohydrates are produced in green plants by photosynthesis and serve as a major energy source in animal diets. Sugars, starches, and cellulose are all carbohydrates.

Substances composed of long chains of oxygen, hydrogen, and carbon molecules. Sugar, starch, and cellulose are all carbohydrates. In the human body, carbohydrates play a major role in respiration; in plants, they are important in photosynthesis.

Note: Carbohydrates in food provide energy for the body and, if present in excess, are stored as fat.
