Enthalpy of proteins

[Protenger]

Hello
I have a very simple question.
Suppose in a protein folding pathway we have two opposite charged
residues seperated by "d" angstrom such that there is a weak
interaction between them. We name it state A, so its enthalpy is Ha.
As protein conformation changes through folding pathway we suppose
"d"
decreases, so interaction between charges become stronger. Now we
name
it State B and its enthalpy as Hb.

My simple question is: is Ha>Hb? or Hb>Ha?


Thanks

Without further knowledge on what you have to do to get from state A to
state B this question can not be answered. Perhaps you have to break
another ionic bond, or get two equal charges uncomfortably close
together?
