<h3>What is the plasma membrane?</h3>

The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.

In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.

For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.
