WebHemoglobin is the protein responsible for carrying oxygen in the blood. It is made up of four polypeptides: two α and two β subunits. One α and one β subunit come together to form a heterodimer, and two of these heterodimers interact to form one hemoglobin molecule. WebOct 27, 2015 · In this context, the electronic structure of carbonmonoxyhemoglobin was easiest to understand. The porphyrin ring of the protein was known to contain four pyrrole N atoms capable of binding to Fe in a plane, with one axial bond to the globin and the other connecting to carbon monoxide.
