Fatty acids are organic compounds containing hydrogen, oxygen, and one of the following groups:
Correct answer: A. Carboxylic
- A. Carboxylic
- B. Amino
- C. Acyl
- D. Sucrose
Explanation
Fatty acids are organic compounds characterized by a long hydrocarbon chain and a terminal carboxylic acid group. The carboxylic group (-COOH) is what makes a molecule a fatty acid, as it imparts acidic properties and is essential for forming ester bonds in lipids. The other options do not represent functional groups that define fatty acids. Amino groups are related to amino acids, acyl groups are derivatives of fatty acids, and sucrose is a sugar, not a functional group.

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.
