<upd_detl>Hematin and hemoglobin are not the same, the former is a derivate of the latter and typically only found in pathological circumstances.
I think GG5 is wrong here, it's 3:1 on hemoglobin.

I can't find much currency for this anyway, most search results are chinese, japanese ones are dictionary sites.
Though the chinese ones also have "hemoglobin" not "hematin".</upd_detl>
