Phosphatidic acid is composed of:
Correct answer: C. 1 glycerol, 2 fatty acids & 1 phosphoric acid
- A. 2 glycerol, 2 fatty acids & 1 phosphoric acid
- B. 2 glycerol, 1 fatty acids & 1 phosphoric acid
- C. 1 glycerol, 2 fatty acids & 1 phosphoric acid
- D. 2 glycerol, 1 fatty acids & 2 phosphoric acid
Explanation
Phosphatidic acid is a fundamental structure in the formation of phospholipids, which are essential components of cell membranes. It consists of one glycerol backbone, two fatty acid chains attached to the first two carbons of the glycerol, and a phosphate group attached to the third carbon. This structure helps in forming the lipid bilayer characteristic of cell membranes. Other options suggesting more than one glycerol or phosphoric acid group are incorrect, as they do not match the standard composition of phosphatidic acid.

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.
