WebProtein denaturation. When a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denaturation of the proteins of egg white by heat—as when boiling an egg—is an example of irreversible denaturation. The denatured protein has the same primary structure as … WebAug 26, 2014 · Polypeptides. When heat is applied to eggs, the different proteins begin to denature. The first is ovotransferrin at 62C-65C. At 80C the protein ovalbumin which makes up 54% of the egg white denatures. As these proteins and their shapes unravel, they become tangled with the other denatured proteins causing it to become firm.

WebThere are more than 40 different proteins in a whole egg, some only located in the white and others predominantly in the yolk. These proteins influence the rate of denaturation and coagulation.
