Detailed explanation-1: -Carbohydrates are composed of carbon, hydrogen, and oxygen and have a general formula that approximates CH2O.

Detailed explanation-2: -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-3: -Carbohydrates are a group of organic compounds containing a ratio of one carbon atom to two hydrogen atoms to one oxygen atom.

Detailed explanation-4: -Carbohydrates make up one of the main classes of biologically-important macromolecules. While carbohydrates can exist in many different forms, they all contain carbon, hydrogen, and oxygen.

Detailed explanation-5: -Carbohydrates are the primary source of energy for living organisms. Carbohydrates are made from carbon, oxygen and hydrogen atoms. Q. Proteins differ from carbohydrates and lipids in that, they always contain nitrogen, carbon, hydrogen and oxygen.
