WebJun 11, 2024 · Denaturation involves unfolding of the polypeptide chains of proteins and of the double helix of nucleic acids, with loss of secondary and tertiary structure; it is caused by heat ( thermal denaturation ), chemicals, and extremes of pH. The differences between raw and boiled eggs are largely a result of denaturation. Compare renaturation. WebThe stability curve of a protein is defined as the plot of the free energy of unfolding as a function of temp. For most proteins, the change in heat capacity on denaturation, or unfolding, is large but approx. const. When unfolding is a 2-state process, most of the salient features of the stability curves of proteins can be derived from this fact.
