The main components of the plasma membrane are phospholipids, proteins and carbohydrates. Phospholipids are amphipathic molecules that are regularly organized in the membrane according to their polarity: two layers of phospholipids form the lipid bilayer, with the polar part of the phospholipids pointing to the exterior part of the layer and the non-polar phospholipid chains toward the interior. Proteins can be found embedded in the lipid bilayer. In addition, there are also some carbohydrates bound to proteins and to phospholipids in the outer surface of the membrane.
