When you cook an egg, sear a steak, or make yogurt, you&rsquo;re denaturing proteins. The change is mostly irreversible and transforms both texture and behavior.</p> <h2 id="what-proteins-look-like">What proteins look like</h2> <p>Proteins are long chains of amino acids (dozens to hundreds), folded into specific shapes held together by weak bonds — hydrogen bonds, van der Waals forces, and ionic attractions. Some proteins fold into compact globules (<a href="https://kvalifood.com/wiki/eggs/">egg</a> proteins), others form long helical fibers (collagen in meat). The folded shape determines what the protein does and how it behaves.</p>
