And so this Salvation Cage creates an energetically, more stable system and lower in energy because the formation of these bonds essentially releases energy and makes it more stable. And by the same reasoning, we see that if we break the bonds, that actually requires energy. And because two thirds of this internal cavity contains the water, when these potassium ions move into this aqueous environment, they do not lose those salvation cages. They do not break those stabilizing interactions. And that's a good thing. So we see that about two thirds of the central cavity is filled with water because of that larger opening and larger amount of space on this side of that protein.
