Cell membranes, which include nuclear, cytoplasmic membranes as well as those of most organelles. They are usually organized in bilayer along with glycolipids and cholesterol. Some proteins (especially cellular receptor) are intercalated in between the components of the bilayer.

The cell membrane is formed by a double layer of phospholipids. They have a hydrophilic head, which points towards the water inside and outside the cell, and a hydrophobic tail which point towards the center of the double layer which contains no water. They consist of two fatty acids and a phosphate group linked to glycerol.
