Why are lipids insoluble in water?

Answer:Lipids are nonpolar molecules, which means their ends are not charged. Because they are nonpolar and water is polar, lipids are not soluble in water. That means the lipid molecules and water molecules do not bond or share electrons in any way. The lipids just float in the water without blending into it.

All non-polar liquids are insoluble in water. Solubilization occurs because the water molecules are like small magnets with a positive pole and a negative pole. When water is mixed with a polar liquid, the negative part of water attracts the positive part of the other liquid and this is solubilized.
