I'll gather some info from a few places. Here's come of the good news!
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?
As an egg is cooked, the egg white proteins (albumins) denature -- unfold
and refold randomly. You would never be able to "uncook" an egg by any
chemical treatment. However, inside every living cell, there are proteins
called chaperones whose job it is to renature proteins. As new proteins
are made, chaperones hang around to supervise (hence the name) and make
sure that new chain of amino acids gets folded correctly. If it should be
folded incorrectly, the chaperone can help stabilize the unfolded state
until the folding is done right.
The calculated true ileal digestibility of cooked egg protein amounted to 91%.
. In this study, it was shown that after ingestion of 25 g of raw egg protein, almost 50% is malabsorbed over 24 h.
Other parts of the study showed that raw egg protein which was absorbed ended up in your urine!
