Detailed explanation-1: -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-2: -Carbohydrates are a class of chemical compounds composed of carbon, hydrogen, and oxygen in 1:2:1 ratio, respectively.

Detailed explanation-3: -Carbohydrates usually have a ratio of two hydrogen molecules for one oxygen molecule, just like water along with the same number of oxygen atoms and carbon atoms. Many molecules that offer energy to living organisms get that energy from some types of carbohydrate, like sugars, starch, or cellulose.

Detailed explanation-4: -Carbohydrate is made up of carbon, hydrogen and oxygen. Its chief function is to provide energy for physiological activities. Starch, sugar, glucose and cellulose are different forms of carbohydrate. Carbohydrate is present in plenty in cereals and tubers in the form of starch.
