And these proteins are usually found inside the polar molecules. And so as a result, all these amino acids that contain these hydrophobic side chain groups are going to display the hydrophobic effect and they're going to basically create this pack structure that will be found inside that protein as compared to outside. Now let's move on to the uncharged hydrophilic polar side chains. So these are the amino acids that essentially contain electric dipole. nomins, they contain a certain polar nature. And because of their polar nature, they will be found on the outside of that protein structure interacting with the polar water solvent molecules.
