As a result of the swapping and symmetry mismatch, there is subunit non-equivalence; even though all the chains are the same chemically, there are two distinct conformations of the subunits. This means there are two matching pairs of subunits. The pairs are illustrated on the left and the morphs referred to below will show on the right: | As a result of the swapping and symmetry mismatch, there is subunit non-equivalence; even though all the chains are the same chemically, there are two distinct conformations of the subunits.

However, each of the subunit '''<span style="color:forestgreen">A</span>'''/<span style="color:cornflowerblue">'''C'''</span> group though is distinct from those of the <span style="color:red">'''B</span>'''/'''D''' group.
