How do phospholipids interact with water molecules?
A) The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).
B) Phospholipids do not interact with water because water is polar and lipids are nonpolar.
C) The polar heads interact with water; the nonpolar tails do not.
D) Phospholipids dissolve in water.

Question

Quizplus · Accepted Answer

Phospholipids have a hydrophilic (water-loving) polar head and a hydrophobic (water-fearing) nonpolar tail. The polar heads interact with water while the nonpolar tails do not, resulting in the formation of a lipid bilayer in an aqueous environment.
