Unlike <a href="https://kvalifood.com/wiki/water-science/">water</a>, <a href="https://kvalifood.com/wiki/lipid-chemistry/">fats</a>, and <a href="https://kvalifood.com/wiki/carbohydrate-overview/">carbohydrates</a> (all relatively stable), proteins drastically change behavior when exposed to heat, acid, salt, or air. This sensitivity is fundamental — proteins are the active machinery of life, assembling and tearing down molecules, transporting materials within cells, forming muscle fibers that move whole animals. Their inherent dynamism is what makes them so responsive to cooking conditions.</p>
