carbohydrates, plural;
  1. Any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body

  1. (carbohydrate) an essential structural component of living cells and source of energy for animals; includes simple sugars with small molecules as well as macromolecular substances; are classified according to the number of monosaccharide groups they contain
  2. A carbohydrate is an organic compound with the empirical formula Cm(H2O)n, that is, consists only of carbon, hydrogen and oxygen, with the last two in the 2:1 atom ratio. Carbohydrates can be viewed as hydrates of carbon, hence their name. ...
  3. (carbohydrate) A sugar, starch, or cellulose that is a food source of energy for an animal or plant; a saccharide
  4. (Carbohydrate) Simple sugars and starches present in foods that provide the body with energy and nutrition.
  5. (carbohydrate) A chemical compound which contains only carbon (C), hydrogen (H), and oxygen (O) and has the general formula Cx (H2O)y. Examples include sugars, starches and cellulose. Plant carbohydrates constitute a major food class and are a basic source of energy for all animals.
  6. (Carbohydrate) a polyhydroxyl ketone or polyhydroxyl aldehyde or a polymer composed of these
  7. (carbohydrate) A class of organic compounds including sugars and starches. The name comes from the fact that many (but not all) carbohydrates have the basic formula CH2O.
  8. (carbohydrate) A sugar molecule. Carbohydrates can be small and simple (for example, glucose) or they can be large and complex (for example, polysaccharides such as starch, chitin or cellulose).
  9. (Carbohydrate) energy-storage compound produced by photosynthesis.
  10. (carbohydrate) 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.
  11. (carbohydrate) glucide / hydrate de carbone
  12. (carbohydrate) in the diet it is broken down to glucose, the body’s principal energy source, through digestion and metabolism. It is stored as glycogen in the liver and muscles. ...
  13. (Carbohydrate) The body’s main energy source, it helps power the body and digest food. The main form of carbohydrate used to generate energy is glucose. If more calories than the body needs are consumed, glucose is converted to body fat.
  14. (Carbohydrate) A major source of energy in the diet. There are two kinds of carbohydrates @ simple carbohydrates and complex carbohydrates. Simple carbohydrates are sugars and complex carbohydrates include both starches and fiber. Carbohydrates have 4 calories per gram. ...
  15. (CARBOHYDRATE) An organic compound, consisting primarily of sugar or starch, that can be turned quickly into caloric energy. Hummingbirds get most of their carbohydrates from flower nectar or sugar water. See also fat and protein.
  16. (CARBOHYDRATE) For plants this means energy (just like it does for humans).
  17. (Carbohydrate) A common chemical in biology given by the formula (CH2O)n
  18. (Carbohydrate) An organic compound, found in food substances such as sugar, cereal and other grain products, fruits and vegetables, that provides fuel for the body.
  19. (Carbohydrate) Carbohydrates are a group of chemical compounds which include sugar, starch and cellulose fibre. Some can be readily burned as energy, while fibre has numerous effects in the gastrointestinal tract. ...
  20. (Carbohydrate) Carbohydrates, often shortened CHO, are often energy giving substances but not always. They are commonly known as sugar, Starch and fibre.
  21. (Carbohydrate) Essential nutrient of the body found in pastas, breads, fruits, vegetables; should comprise the majority of calories in a runner’s diet; stored in the body as glycogen in the muscles and liver; overconsumption is converted to fat.
  22. (Carbohydrate) Mainly sugars and starches. One of the three main Macronutrients (macro=big). Important for storing and converting energy in the body. The body has only a limited storage capacity for carbs unlike fat storage which is virtually unlimited. ...
  23. (Carbohydrate) One of the common elements found in organic matter and living things.
  24. (carbohydrate) Very abundant compounds, usually an aldehyde or ketone derivative of a polyhydric alcohol, particularly of the pentahydric and hexahydric alcohols. They are so named because the hydrogen and oxygen are usually in the proportion to form water with the general formula Cn(H2O)n. ...
