Detailed explanation-1: -Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules-large molecules necessary for life that are built from smaller organic molecules.
Detailed explanation-2: -Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits.
Detailed explanation-3: -Biomolecules include large macromolecules (or polyelectrolytes) such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites and natural products.
Detailed explanation-4: -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.
