AS Biology Coursework - protein/copper sulphate watch

    I'm doing the effect of copper sulphate on egg albumen (an example of a protein).

    The protein is denatured as its ionic bonds are broken (going from tertiary to secondary structure) but I don't know how exactly it works. Could anyone tell me/direct me to a site that could explain?



    Copper ions form strong bonds with carboxylate anions on the amino acids that form part of the peptide bond. This forms a new set of ionic bonds, disrupts the peptide links.
    Changes the structure from tertiary to secondary.

    Hope that helps!!
