Myoglobin binds how many oxygen
WebMyoglobin is a low-molecular weight protein of 16,000 Da that contains one heme and binds one molecule of O 2 per molecule of protein. Tissue content of myoglobin depends on the … Like hemoglobin, myoglobin is a cytoplasmic protein that binds oxygen on a heme group. It harbors only one globulin group, whereas hemoglobin has four. Although its heme group is identical to those in Hb, Mb has a higher affinity for oxygen than does hemoglobin. This difference is related to its different role: … See more Myoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. Myoglobin is distantly related to See more Myoglobin is released from damaged muscle tissue (rhabdomyolysis), which has very high concentrations of myoglobin. The released myoglobin is filtered by the kidneys, but is toxic to the renal tubular epithelium and so may cause acute kidney injury. … See more • Cytoglobin • Hemoglobin • Hemoprotein • Neuroglobin See more • Collman JP, Boulatov R, Sunderland CJ, Fu L (Feb 2004).
