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…

It is observed that as temperature is increased, most protein molecules gofrom their defined, folded state into a random-coil, denatured state thatexposes more hydrophobic surface area than is exposed in the folded state.(a) Given what you have learned so far about ΔH and ΔS, explain why thisis reasonable. (b) Sometimes, however, proteins denature as temperature is decreased.How might this be explained?
Proteins can be precipitated out of aqueous solution bythe addition of an electrolyte; this process is called “saltingout” the protein. (a) Do you think that all proteins wouldbe precipitated out to the same extent by the same concentrationof the same electrolyte? (b) If a protein has beensalted out, are the protein–protein interactions stronger orweaker than they were before the electrolyte was added?
