How do hydrophilic molecules react with water

WebWater, which is polar, therefore sticks to itself and it sticks to the phosphates on the outside and the inside surfaces of the membrane, but it is repelled (just the same way that oil and water repel each other) from the center of the membrane. The heads are hydrophilic (water loving) and the tails are hydrophobic (water fearing). WebThis is because the water is able to form hydrogen bonds with the hydroxyl group in these molecules, and the combined energy of formation of these water-alcohol hydrogen bonds is more than enough to make up for the energy that is lost when the alcohol-alcohol hydrogen bonds are broken up.
