Question

Lipids are water insoluble because lipid molecules are

• A. Hydrophilic
• B. Neutral
• C. Zwitter ions
• D. Hydrophobic

Hint:

Non-polar substances like lipids do not dissolve in polar solvents such as water.

Answer 1

The Correct Option is D

Step 1: Lipid molecules consist mainly of long hydrocarbon chains, which are non-polar in nature.
Step 2: Water is a polar solvent and dissolves substances that are polar or charged.
Step 3: Since lipids are non-polar and hydrophobic, they do not dissolve in water. Therefore, lipids are water insoluble because they are hydrophobic.
