So it contains a full charge. Now, because this contains a charge, it can interact via hydrogen bonds with these nearby water molecules and these bonds are shown in purple. Now, these interactions between the polar water and this polar head of the ionized fatty acid, those interactions are good, they are energetically stabilized, they are energetically favorable. But all these other water molecules that surround this hydrophobic red chain basically cannot interact in the same energetically favorable way because this is non polar and the water molecules are polar. And so ultimately all these water molecules remain trapped and cannot interact any favorable bonds and that is not a stabilizing system. And so what happens is when we have many of these ionized fatty acids in an aqueous environment, they will form these micelles, these globular spherical structures in which the outside of the sphere, we basically have all these heads because their polar align themselves in a way that they point towards the aqueous environment.
