How does NH4SO4 affect water structure? Whatdoes this have to do with protein solubility?I thought the answer was that NH4S04 attractsH2O so the protein doesn't bind to H2Oallowing the protein to bind to each other. Butthe answer given is, orders water locally tobecome more ice-like.Can someone explain?

One of the factors that determine the solubility of proteins in solution is the concentration of…
