Question - After proteins of denatured, is it possible
for them to go back to their original formation? Like the white of eggs
after being cooked, is it possible for those proteins to renature?


Under some conditions certain proteins can renature...eg. A change in pH
will cause many proteins to somewhat unravel which is reversable on return
to "normal" pH. Heat denaturation can also be reversible if mild...PCR uses
this in a sense. As for albumin (egg white), heating to a near boil
permanently denatures the albumin.
