3 Phospholipid Bilayer Phospholipid has two fatty-acid chains attached to its backbone. One end is strongly nonpolar while the other end is strongly polar. polar head oriented toward water and nonpolar tails oriented away from water bilayer is stable because water’s affinity for hydrogen bonding never stops
