(Phys.org) —Water is crucial to the functioning of the body, even on very small scales. The ubiquitous liquid is key to the structure, folding and stability of proteins, but one of the still unanswered questions in the study of the structure and function of proteins and DNA is their exact relationship to their water environment. All of the molecules in our bodies function in water, but until now, we haven't had a lot of experimental techniques to understand what water is doing or where it is binding to the interior surfaces of proteins.
