And as we continually destabilize the different segments of our protein, those segments destabilize other segments. So as these move apart, these begin to move apart. And so these interactions begin to break, these interactions begin to break. And so eventually we form intermediate state B, in which all these bonds between these beta sheets and these beta sheets eventually break, and the bonds between the beta sheets and these alpha helixes break as well. And so intermediate state B describes only the secondary structures involved. So we have these four beta pleated sheets and these three alpha helices.
