Assume that some protein molecule, in its folded native state, has one favored conformation. But when it is denatured, it become

s a "random coil", with many possible conformations.
How will the contribution of ΔS for native → denatured affect the favorability of the process? What apparent requirement does this impose on ΔH if proteins are to be stable structures?

Answer:

Gibbs Free Energy is given by the next equation: ΔG = ΔH - TΔS, where

ΔH - <u>change</u> in enthalpy

T - temperature in Kelvin

ΔS - <u>change</u> in entropy

ΔG can be:

  • ΔG>0 positive(not spontaneous reaction)
  • ΔG<0 negative(spontaneous reaction)
  • ΔG=0(in equilibrium).

→ When the proteins are denatured, the entropy of the system increases. Therefore, the ΔS also increases and becomes more positive.  

→ From the equation we see that positive value of ΔS contributes to negative value of ΔG.

The proteins are stable when there is no spontaneous reaction, thus, the ΔG>0 is required. Which means that ΔH has to be large and positive to counteract the influence of ΔS.

Calculate the pH of a 2.0 M H2SO4 solution.
noname [10]
 <span>H2SO4 gives 2 moles oh H+ per mole of acid 

[H2SO4] = 2M so [H+] = 4M 

pH = -log(4) = -.6 

Therefore, the pH </span><span>of a 2.0 M H2SO4 solution is -0.6
