Usage: biochemistry
2. adding a substance to alcohol to make it unfit for drinking
Usage: chemistry

1. the process of changing the natural structure of proteins or other molecules
Usage: biochemistry

Examples

• Heat is denaturing the proteins in the egg white as it cooks.
• The laboratory is denaturing the alcohol to prevent consumption.
• Acid rain is denaturing proteins in fish living in affected lakes.
• The denaturing of enzymes occurs at high temperatures.
• Scientists studied the denaturing effects of various chemicals on DNA.
• Ethanol denaturing makes industrial alcohol toxic to drink.
• The denaturing process destroyed the protein’s biological activity.
