Description

An irreversible alteration of a protein's structure that can be caused by heat, water, alkalis, acids and detergents. In denaturation, hydrogen bonds break causing the highly ordered structure of collagen to change into a disordered gelatin mass. Denaturation of parchment and leather has been measured using infrared spectroscopy, x-ray diffraction, and liquid chromatographic techniques (Derrick, 1999)
