Just like her parents, Cell Membrane or "Plasma Membrane" loves to call her allies on their nicknames such as: integral protein as "transmembrane protein"; cholesterol as "sterol"; carbohydrates attached to lipid as "glycolipid"; and carbohydrates attached to protein as "glycoprotein". Sophisticated, choosy, attacker, are just some of Cell Membrane's attributes. All these are made possible because of her treasures: phospholipid bilayer, cholesterol, proteins, and carbohydrates which the illustrators J Singer and G. Nicolson painted her as a "Fluid Mosaic Model".
