Web9 okt. 2024 · Myoglobin is a small oxygen-binding protein found in muscle cells. Its functions primarily in storing oxygen and facilitating oxygen diffusion in muscle tissue. Myoglobin is a single-chain globular protein that consists of 153 amino acids and a heme group (an iron-containing porphyrin). The globular structure of myoglobin consists … 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 … Meer weergeven 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 hemoglobin. … Meer weergeven Myoglobin is released from damaged muscle tissue (rhabdomyolysis), which has very high concentrations of myoglobin.
