What Are Lipids? — Structure & Function

Based on what you know about the cohesion of water, why do you think lipids are not soluble in water?

Choose one answer

Option A: A

Water has strong cohesion because of hydrogen bonding. Lipids are nonpolar and cannot undergo hydrogen bonding; they can't mix with water.

Option B: B

Water has weak cohesion because of hydrogen bonding. Lipids are nonpolar and have a high cohesion so they don't mix with water.

Option C: C

Water has strong cohesion because of covalent bonding. Lipids are nonpolar and cannot undergo covalent bonding so they don't mix with water.

Option D: D

Water has weak cohesion because of lack of hydrogen bonding. Lipids are polar and have a high cohesion so they don't mix with water.
