With some laboratory tests, the results obtained for healthy people can vary somewhat from person to person. Factors that can cause person-to-person variation in laboratory test results include a person's age, sex, race, medical history, and general health.
It has a formula of C12H22O11. A carbohydrate is a biological molecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogenâoxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cm(H2O)n (where m could be different from n). This formula holds true for monosaccharides.
The name carbohydrate reveals the chemical make up of this nutrient class. Indeed, carbo means carbon, while hydrate means water, a combination of hydrogen and oxygen molecules. All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.
