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?



Replies:
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.
