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. And this protein is shown on the board with this brown color. So this is the alpha hemoglobin stabilizing protein. Now, this is a single monomer of the alpha polypeptide chain of the hemoglobin molecule.
