<strong>3.3</strong> Cell Membrane<br />

<strong>3.3</strong> Assessment: Hwy do phospholipids form a<br />

double layer?<br />

Phospholipids form a double layer in response to the<br />

presence of polar water molecules surrounding them.<br />

The polar heads of phospholipids interact with the water<br />

inside and outside the cell, forming transient hydrogen<br />

bonds. The nonpolar tails are repelled by water and<br />

interact with each other inside the membrane.
