What is Denaturation?
The process by which a protein or nucleic acid loses its native three-dimensional structure due to disruption of stabilizing interactions. Denaturing agents include heat, extreme pH, and chemicals like urea. Denatured proteins typically lose their biological activity.

The process by which a protein or nucleic acid loses its native three-dimensional structure due to disruption of stabilizing interactions. Denaturing agents include heat, extreme pH, and chemicals like urea. Denatured proteins typically lose their biological activity.
Denaturation is exploited in cooking (egg white coagulation, meat cooking), sterilisation (autoclaving denatures microbial proteins), analytical biochemistry (SDS-PAGE separates proteins by size after denaturation with SDS), PCR (heat denaturation of DNA double helix), and in the production of insol…
Denatured proteins can be allergenic or immunogenic. Industrial processes using heat to denature pathogens must reach validated temperatures (pasteurisation: 72°C/15 s; autoclaving: 121°C/15 min). Chemical denaturants (formaldehyde, urea, guanidinium) are toxic or hazardous.
The formula or notation for Denaturation is: Protein unfolding: ΔG_unfolding < 0 under denaturing conditions
