Hofmeister series salts are known to effect protein denaturation. What are these Hofmeister series salts? What is the effect on proteins?
Homework Answers
Hofmeister series or lyotropic series is classification of ions in order of their ability to salt out or salt in protein.
It is a series of salt that have consistent effects on the solubility of proteins and on the stability of their secondary and tertiary structure.
Early members of the series increase solvent surface tension and decrease the solubility of non polar molecule ( salting out), in effect,they strengthen the hydrophobic interaction.
By contrast,later salts in series increase the solubility of non
polar molecule(salting in) and decrease the order in water,in
effect,they weaken the hydrophobic effect. The salting out effect
is commonly exploited in protein purification through the use of
ammonium sulfate precipitation.

5. In an equilibrium denaturation experiment, one makes up a series of different protein solutions, 1, 2, ..., M, having different amounts of urea, a denaturing agent, x1, x2, ..., XM. Then, for each particular solution, having denaturing agent in amount x, one measures the proportion f(x) of native protein molecules and the proportion fo(x) = 1 - fr of denatured protein molecules. Increasing the denaturing agent increases the population of Drelative to N. In the absence of denaturing agent,...
