A protein that is folded into a three-dimensional structure and soluble in water will likely have hydrophobic amino acids buried in the core of the protein, away from the water. Therefore, the group of amino acids that would be most likely to be found in the core of such a protein are the hydrophobic amino acids, which include isoleucine (I), methionine (M), and valine (V).
