Suppose you take some raw egg white and mix it into a beaker of room temperature water to form a solution. If you boil the water, a precipitate will form in the water. Explain why heating the protein solution created the precipitate?

Heat results in coagulation of protein chains so white precipitate is formed.

Explanation:

On heating, the hydrogen bond that stabilize the protein conformation breaks. The breaking of hydrogen bonds results in unfolding the tertiary structure of protein. The unfolded peptides then reform into new conformation and form a coagulum. This explains why a white precipitate is formed when protein solution is heated.
