A question about Protein

... ones. "But then why does urea or guanidine hydrochloride solubilize proteins; don't they also denature them?" Yes, they do, but the dissolution of urea or guanidineHCL in water, though it is a spontaneous process (deltaG < 0), there is a negative entropy contribution as these ...
