How do phospholipids interact with water molecules?

• Phospholipids dissolve in water.

• The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).

• The polar heads interact with water; the nonpolar tails do not.

• Phospholipids do not interact with water because water is polar and lipids are nonpolar.

• Amino group

• Carbonyl group

• Hydroxyl group

• Carboxyl group

• Sulfhydryl
