At the end of our reaction, when all the beta subunits are used up, we're going to have an excess amount of alpha submunes left over inside our blood plasma. And the problem with that is these alpha subunits can form aggregates because they can bind to one another to form these complexes. And these complexes will become insoluble. And what that means is they will precipitate out of the blood plasma, and that can form and that can cause many different types of problems. So what does our body do to prevent the aggregation and the precipitation of these alpha complexes? Well, inside red blood cells, we have these special proteins known as the alpha hemoglobin stabilizing protein, or simply Ahsp.
