Waxes are formed by the combination of fatty acids with:
Correct answer: A. Alcohol
- A. Alcohol
- B. Glycerol
- C. Serine
- D. Cysteine
Explanation
Waxes are a type of lipid formed by the esterification of long-chain fatty acids with long-chain alcohols. This combination results in hydrophobic molecules that are solid at room temperature. In contrast, glycerol forms triglycerides with fatty acids, while serine and cysteine, being amino acids, do not typically combine with fatty acids to form waxes.

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.
