WebMyoglobin (Mb) is an iron-containing heme protein that is present predominantly in the sarcoplasm of skeletal and cardiac muscles. Due to the presence of heme moiety, myoglobin serves as a carrier and store for oxygen in muscle cells of the body. Myoglobin has more affinity for oxygen as compared to hemoglobin. WebUnder the same conditions myoglobin, were it be used in red blood cells as an oxygen carrier, would release much less. Incidentally the Figure linked to shows a comparison between haemoglobin and a hypothetical protein which shows 50% saturation at the same concentration of oxygen but which binds oxygen non-cooperatively (like myoglobin).
