denaturation

of a macromolecule
https://doi.org/10.1351/goldbook.D01586
The process of partial or total alteration of the native structure of a macromolecule resulting from the loss of tertiary or tertiary and @S05530@ that is a consequence of the disruption of stabilizing weak bonds. Denaturation can occur when @P04898@ and @N04245@ are subjected to elevated temperature or to extremes of pH, or to non-physiological concentrations of @S05447@, organic solvents, urea or other chemical agents.
