Explanation:
Detailed explanation-1: -Nitrogen in the reduced form is the major component of the three most important biological macromolecular structures: (i) proteins/polypeptides, (ii) DNA and RNA, and (iii) polymers of amino sugars.
Detailed explanation-2: -Nitrogen is in all amino acids and nucleotides, and therefore in all proteins and nucleic acids.
Detailed explanation-3: -Proteins, carbohydrates and lipids are made from three basic molecules: carbon, hydrogen and oxygen. However, all proteins contain an element not found in carbohydrates and lipids is nitrogen.
Detailed explanation-4: -All the biological macromolecules contain carbon, hydrogen and oxygen. However, most do not contain nitrogen.
