Don't boiled eggs harden due the formation of covalent bonds?
"As the temperature increases, the proteins gain enough energy to form
new, stronger bonds (covalent) with other protein molecules."
"As the proteins form these new, strong bonds, the water that
surrounded each protein molecule when the egg was liquid is forced
