Carbohydrate Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
A carbohydrate is a large biological molecule, or macromolecule, consisting only of carbon (C), hydrogen (H), and oxygen (O), usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula  (where m could be different from n). Some exceptions exist; for example, deoxyribose, a sugar component of DNA, has the empirical formula C5H10O4. Carbohydrates are technically hydrates of carbon; structurally it is more accurate to view them as polyhydroxy aldehydes and ketones.
