WebHemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen. It is the iron in hemoglobin that gives blood its red color. It is easier to bind a second and third oxygen molecule to Hb than the first molecule. WebHemoglobin, a protein in your red blood cells, binds oxygen in your lungs, and distributes oxygen throughout your body. Hemoglobin has a very high affinity for oxygen. However, it has a HIGHER affinity for CO. The usual function of hemoglobin is to bind oxygen (O 2) and take it to a place in the body that needs oxygen, and then releases the oxygen.
