Thus, total absorbance correlates with the total … WebHaemoglobin (also spelled hemoglobin) is iron containing compund that binds to oxygen gas. It is found in the red blood cells of vertebrates. It transports oxygen from the respiratory organ, the lungs, to the different cells of body. It is a protein that contains a quaternary structure made up of 4 sub-units.

WebHemoglobin is the oxygen-carrying pigment in the red blood cells that transports oxygen from the air in the lungs to the tissue fluid around the cells. Recall that one molecule of hemoglobin can bind four molecules of oxygen. One oxygen molecule is attached to each of the four heme groups present in hemoglobin. WebJul 20, 1998 · hemoglobin, also spelled haemoglobin, iron -containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates —that transports oxygen to the tissues.
