Nutritional components of egg white

Egg white (also known as protein) refers to a transparent colloidal substance which is wrapped around egg yolk and composed of protein. So it is also called protein, as opposed to egg yolk. Protein will solidify into a white solid when heated, hence its name. Protein is as shockproof, moisturizing and protective as mammalian amniotic fluid. If you mix the egg whites with a high-speed whisk, they will be as elastic as a sponge, which is the first step in making a cake.
