And so what happens is to prevent the aggregation of these alpha complexes, our cells use the alpha hemoglobin stabilizing protein to basically form this complex that is stable enough and soluble in the blood plasma. So the alphahsp complex, and then when we have enough beta subunit, so when the beta subunits are produced by the red blood cells, they can then begin displacing this molecule and forming the alpha beta dimer. And this dimer is more stable than this dimer. That's precisely what drives the equilibrium towards this side, towards this molecule. And notice that our beta unit binds onto that alpha unit on the same side, on the same face as the Ahsp molecule. So to conclude, to prevent aggregation of these alpha subunits inside our blood blood plasma, our body, our red blood cells use this special protein, we call alpha hemoglobin stabilizing protein to form these dimers that are soluble in water in our blood plasma.
