Quizplus · Accepted Answer

Phospholipids are amphipathic, meaning they have both polar and nonpolar regions. The polar head group is hydrophilic and interacts with aqueous environments while the nonpolar tail region is hydrophobic and interacts with nonpolar environments. This allows them to form effective barriers between the aqueous cytosol and extracellular fluid.
