Is frying an egg a chemical change?

Frying an egg is a chemical change.

When an egg is fried, the proteins in the egg white coagulate and the yolk thickens. This is due to the chemical reactions that occur when the egg is heated. The heat causes the proteins to break down and form new bonds with each other, resulting in the change in texture. Additionally, the Maillard reaction, which is a chemical reaction between amino acids and sugars, occurs when the egg is fried, giving it a brown colour and a characteristic flavour.
