How do phospholipids interact with water molecules?

Question

Quizplus · Accepted Answer

Phospholipids have a polar head and a nonpolar tail. The polar head contains a phosphate group and is hydrophilic (water-loving). The nonpolar tail contains fatty acids and is hydrophobic (water-fearing). Therefore, when placed in water, the polar heads interact with water, while the nonpolar tails do not. This is due to the fact that water is a polar molecule and can form hydrogen bonds with the polar heads of the phospholipids, while it cannot do so with the nonpolar tails. This interaction results in the formation of a lipid bilayer, which is the basis of cell membranes.
