So twice as less. Now, why is that a problem within our red blood cells? Well, because inside any hemoglobin molecule, we have a one to one correspondence, one to one combination between the alpha and beta subunits. 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.
