    In Anfinsen's original experiment, he denatured ribonuclease with 8M urea (this is a dissociating solvent and breaks all weak bonds). 2-mercaptoethanol is a reducing agent and reduces disulphide bridges to SH groups (sulphydryl), thus breaking them. This converts the enzyme to a random ...

    Solution Summary

    The solution explains why pro-insulin can be refolded but not insulin. The Anifansen's experiments with ribonuclease are given.
