Egg white is largely a protein called albumin, and heat changes it from a translucent, soluble form to a solid white mass. In cooked egg white, albumin’s exquisitely folded chain of amino acids is shaken apart and entangled with others. This loss of structure in a protein molecule is called denaturation. The humble act of frying ...
