- A. Cholesterol, Guanine
- B. Amino acid NH-2
- C. Nucleotide:Adenine
- D. Nucleoside: Uracil

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
