Question

Denaturation of Egg Albumin Questions: Explain how does egg albumin protein changes when it denatured? (Use your observations as a basis for your answer). What other methods could you use to denature egg albumin protein (egg whites)? In an emergency, persons who ingest heavy metal ions such as silver, lead, or mercury can be given egg whites or milk as an immediate measure limit to the toxicity until they can be transported to the hospital for further treatment. Why is giving them milk or egg whites a good idea?

Explanation / Answer

1) When an egg is cracked and open, the "white substance" is appear, which is translucent and runny. It flows like a liquid, but upon heating the white material harden and turns white. The change in viscosity and color is an indication that the proteins have been denatured.

2) Changes in pH and Protonation of the amino acid residues;

Changes in salt concentration

3) Egg white and milk are used as an antidote to heavy metal ions. Heavy metal denature the protein. A protein (i.e. milk or egg white) is administered to precipitate the poisonous heavy metal salts. Then an emetic is given to precipitate the metal protein and discharge it from the body through vomiting.
