Usage: Historical and regulatory context

Examples

• Heat-induced denaturations of proteins can be observed under a microscope.
• The denaturations of DNA strands occur when exposed to extreme temperatures.
• Scientists study the denaturations of enzymes to understand their function.
• Multiple denaturations and renaturations of the sample were performed in the experiment.
• The denaturations of alcohol during Prohibition made it unsafe to drink.
• Chemical denaturations of biological molecules are essential in many laboratory procedures.
