WebHemoglobin is a heterotetrameric oxygen transport protein found in red blood cells (erythrocytes), whereas myoglobin is a monomeric protein found mainly in muscle tissue where it serves as an intracellular storage site for oxygen. WebThe principal functions of hemoglobin and myoglobin are oxygen transport (case of hemoglobin) and its storage in muscles (case of myoglobin). Other hemoproteins play the role of electron transfer molecules (case of cytochromes).
