The cell membrane is a biological membrane that surrounds (protects) a cell and separates the contents of the cell from its surrounding environment. The chemical structure that makes up the cell membrane include; phospholipids (lipid molecules that contains a phosphate group head and two fatty acid tails), glycolipids (lipids with carbohydrate), proteins and cholesterol. The phospholipids forms a double layered membrane around the cell.
