Lipids are insoluble in water because lipid molecules are:
Correct answer: B. Hydrophobic
- A. Hydrophilic
- B. Hydrophobic
- C. Neutral
- D. Amphipathic
Explanation
Lipids are insoluble in water because they are hydrophobic. Hydrophobic substances do not interact well with polar water molecules. Instead, hydrophobic molecules tend to cluster together, avoiding contact with water. This is why lipids, which are mainly composed of long hydrocarbon chains, do not dissolve in water.Option A, hydrophilic, is incorrect because hydrophilic substances are attracted to water and generally dissolve well in it due to their polar nature. Option C, neutral, refers to the charge state of molecules and not their solubility in water. Many neutral molecules can still be water-soluble. Option D, none of these, is incorrect because the correct answer is provided in Option B.

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.
