Glycerol, fatty acids and phosphoric acid gives rise to:
Correct answer: B. Phosphatidic acid
- A. Phospholipid
- B. Phosphatidic acid
- C. Phosphatidylcholine
- D. Phosphatidylethanolamine
Explanation
The correct answer is phosphatidic acid. When glycerol, fatty acids, and phosphoric acid combine, they form phosphatidic acid, which is the simplest phospholipid and serves as a precursor for more complex lipids such as phospholipids. Phospholipids like phosphatidylcholine and phosphatidylethanolamine require additional components, such as a nitrogenous base (choline or ethanolamine, respectively), which are not part of the initial combination described in the question.

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.
