Detailed explanation-1: -Proteins, carbohydrates and lipids are made from three basic molecules: carbon, hydrogen and oxygen.
Detailed explanation-2: -Carbohydrates and lipids both contain carbon (C), hydrogen (H), and oxygen (0); proteins contain these three elements plus one or more from nitrogen (N), sulphur (S) and phosphorous (P).
Detailed explanation-3: -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-4: -Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Detailed explanation-5: -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.
