Non covalent interaction in which a fatty acid tail interacts with water. Model provide permeability and fluidity barrier o membranes are made up of phospholipids embedded with proteins transport receptors , enzymes structure are. Are hydrophobic hydrophilic hydrophobic non polar regions . Lipids are exposed to water it the order hydrophobic of water groups molecules. When hydrophobic groups cluster free to run around in a more disorder together state the water is. Gibb "s free energy measure of total energy of system. Entropy measures the freedom to move of components of a system measures how strongly bonded a system is the largest contributor to system stability in bilayer formation is entropy.
