Phosphatidic acid is composed of :
Correct answer: A. Glycerol + 2 Fatty acid + Phosphoric acid
- A. Glycerol + 2 Fatty acid + Phosphoric acid
- B. Glycerol + Fatty acid + Phosphoric acid + N-base
- C. 2 Glycerol + Fatty acid + Phosphoric acid
- D. Glycerol + Fatty acid + 2 Phosphoric acid + N-base
Explanation
Phosphatidic acid is a crucial intermediate in lipid biosynthesis and serves as a fundamental building block for phospholipids. It is composed of a glycerol backbone bonded to two fatty acid chains and one phosphoric acid group. This specific structure distinguishes it from other lipid molecules that may contain additional components, such as nitrogenous bases or extra glycerol or phosphoric acid groups. Options B, C, and D propose structures with constituents not found in phosphatidic acid, leading to their incorrectness. Option B incorrectly includes a nitrogenous base, Option C incorrectly proposes two glycerol molecules, and Option D inaccurately suggests two phosphoric acid groups and a nitrogenous base.

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.
