What do cell membranes consist of?

Cell membranes consist of a phospholipid bilayer, which is made up of two layers of phospholipid molecules. Embedded within this bilayer are proteins that help regulate the passage of ions and molecules in and out of the cell. Additionally, cell membranes may contain cholesterol molecules that provide stability and fluidity to the membrane.
