The egg white is about 12 percent protein, and also the egg yolk itself is about 16 percent protein. Any alteration to the structure of this protein change the structure of the whole egg.

Denaturation means the process by which the chains of amino acids are changed from their original (or native) state chemically. The heat denatures the protein by disrupting some of its bonds that held the molecule into shape. In the case of hard-boiled eggs, the proteins clump together and solidify, causing the egg white and yolk to harden.
