Denaturation Of Egg Albumen
Background Information
Egg albumen is the outer fluid layer of the egg. ...
Albumen is a globular protein; these are made of chains folded into a compact structure. ...
Denaturation
Anything that stops the protein from functioning is denaturation, which may be evident as a colour change, or a change in solubility. This could be caused by excessive heating, a solvent, or oxidation
Why the albumen denatures with CuSO4
Cations from the copper from strong bonds with carboxylate anions on the amino acids, which form the peptide bonds. ... The positive copper ions also affect the proteins electrical polarity, thus increasing its insolubility and often causing it to precipitate out of solutions when albumen is exposed to copper sulphate, the copper ions disrupt the structure, and it re-forms as a fibrous protein, precipitating out of solution and becoming opaque. The more denaturation that occurs, the more protein precipitates, and the cloudier the solution gets, until the cross on the tile fully disappears.
