The process of partial or total alteration of the native structure of a macromolecule
resulting from the loss of tertiary or tertiary and
secondary structure that is a consequence of the disruption of stabilizing weak bonds. Denaturation can
occur when
proteins and
nucleic acids are subjected to elevated temperature or to extremes of pH, or to non-physiological
concentrations of
salt, organic solvents, urea or other chemical agents.
