Detailed explanation-1: -Proteins are the polymers of amino acids and have C, H, O, N and S. Carbohydrates and nucleic acids have C, H, O, N, P and S.

Detailed explanation-2: -Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

Detailed explanation-3: -There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO).

Detailed explanation-4: -11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits.

Detailed explanation-5: -Plastics, resins, many synthetic and natural fibres (e.g., nylon and cotton), rubbers, and the biologically important proteins and nucleic acids are among many substances that are made up of macromolecular units. Macromolecules are composed of much larger numbers of atoms than ordinary molecules.
