All of the following are true about lipids except:
Correct answer: B. They are polymers of fatty acids
- A. They store a high amount of energy
- B. They are polymers of fatty acids
- C. They play an important role in insulation
- D. They are mostly hydrophobic
Explanation
Option B is correct. Lipids are not polymers of fatty acids because they do not consist of repeating units. Instead, lipids are composed of fatty acids linked to molecules like glycerol. This differentiates them from true polymers like proteins or nucleic acids. Option A is incorrect because lipids indeed store a high amount of energy, making them efficient energy reserves. Option C is incorrect as lipids do provide insulation, which helps in temperature regulation. Lastly, Option D is incorrect because lipids are mostly hydrophobic, a trait essential for their role in cellular structures and functions.

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.
