Is frying an egg denaturation?

The energy added to the egg makes the proteins unravel and open up. This is called denaturation. The proteins lose their native structure and become long, unfolded strands wiggling around. … And when we fry our eggs, we are purposefully denaturing proteins and forming a gel.

What happens to an egg when it is fried?

Heat ’em up

Heat energy agitates the egg-white proteins, making them bounce around and hit water molecules and other proteins. These collisions break the weak bonds that held the protein globs curled up, allowing the amino acid chains to partly unwind – a process called ‘denaturing’.
