Now let's move on to experiment number three. So in experiment number three, what he saw is if he took this scrambled enzyme and he added a tiny amount of beter mccaptoethanol. So basically we have a beaker that contains our scrambled enzyme and we don't have any type of agent inside that beaker. And now we add a trace amount of beta mecapto ethanol. So what he found was because we had a tiny bit amount of this catalyst, this catalyst essentially catalyzed the breakage of these incorrectly paired disulfide bonds. And eventually because of thermodynamics, we formed this native enzyme.
