| Jun 25, 2017 at 9:28 | comment | added | Confusedbyeverything | Here is my confusion: how do the changes in the temperature/crystal formation change the structure of the protein and why would this favor the formation of an insoluble form ? I understand how PH, salts, inter-molecular forces, can effect protein folding. I can even understand how temperature can denature a protein by offering it more energy to undergo different chemical reactions, but what is the underlying concept that explains the change from soluble to insoluble when we decrease the temperature? PS I am not a chemistry major so thanks in advance | |

| Jun 25, 2017 at 6:25 | comment | added | Nicolai | @Confusedbyeverything I already explained that: the change in temperature/crystal formation changes the structure of the protein, this in turn changes which residues of the proteins interact with the water/solvent, which changes its solubility | |
| Jun 25, 2017 at 6:05 | comment | added | Confusedbyeverything | I am asking what physical and or chemical properties of the water and or the protein. make a protein go from being soluble to insoluble in a POLAR solvent such as water. Regardless of the temperature of the solution, the solvent remains polar. So why would a temperature decrease change how a protein interacts with a POLAR solvent | |
