The coagulation of egg white on boiling and the curdling of milk due to the formation of lactic acid by bacteria are common examples of denaturation, causing changes in the structure and activity of proteins.
Provide examples of denaturation in everyday scenarios, mentioning the impact on proteins.

Cooking an egg exemplifies denaturation; heat disrupts egg white proteins, altering their structure from transparent liquid to opaque solid. In milk, heating causes denaturation of whey proteins, forming curds in cheese-making. Acidic conditions in the stomach denature dietary proteins, aiding digestion. Even whipping cream involves denaturing milk proteins to create a stable foam. High temperatures during grilling denature muscle proteins in meat, altering texture and taste. These everyday scenarios illustrate denaturation’s impact, breaking down complex protein structures, often leading to desirable changes in food properties like texture and taste.
