Detailed explanation-1: -Answer and Explanation: The classes of macromolecule that contain the most phosphorus are equally the nucleic acids and the lipids. Nucleic acids in DNA or RNA contain a single phosphate group, which contains phosphorus.
Detailed explanation-2: -Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). Both types of nucleic acids contain the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus.
Detailed explanation-3: -We have lipids, Proteins, nucleic acids and carbohydrates, which one has a phosphate group.
Detailed explanation-4: -Phosphorus is found in both DNA and RNA, as it is the nucleic acid’s backbone. The presence of phosphoric acid causes nucleic acids to be acidic. Phosphate + sugar + nitrogenous base = nucleic acid. DNA is made up of deoxyribose, a nitrogenous base, and phosphate.
Detailed explanation-5: -Lipids are the only macromolecules that are not polymers. Lipids are diverse in structure and function, but all have in common that they are hydrophobic-that is, they are nonpolar and do not dissolve in water.
