Detailed explanation-1: -Carbohydrates are composed of carbon, hydrogen, and oxygen and have a general formula that approximates CH2O. They are polyhydroxy aldehydes or ketones or form polyhydroxy aldehydes or ketones when hydrolyzed. Carbohydrates occur as monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Detailed explanation-2: -The common attributes of carbohydrates are that they contain only the elements carbon, hydrogen and oxygen, and that their combustion will yield carbon dioxide plus one or more molecules of Water.

Detailed explanation-3: -Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.

Detailed explanation-4: -Carbohydrates are the compounds made up of carbon, hydrogen and oxygen. Carbohydrates are the energy giving food, and they are present mainly in cereals, sugar and potatoes. The simplest carbohydrate is glucose.

Detailed explanation-5: -All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen.
