Myoglobin - Physiopedia
WebThese fibers have a rich capillary supply, numerous mitochondria and aerobic respiratory enzymes, and a high concentration of myoglobin. Myoglobin is a red pigment, similar to the hemoglobin in red blood cells, that improves the delivery of oxygen to the slow-twitch fibers. WebMyoglobin breaks down into substances that can damage kidney cells. Rhabdomyolysis may be caused by injury or any other condition that damages skeletal muscle. Problems … Myoglobin is a sensitive marker for muscle injury, making it a potential marker for heart attack in patients with chest pain. However, elevated myoglobin has low specificity for acute myocardial infarction (AMI) and thus CK-MB , cardiac troponin , ECG , and clinical signs should be taken into account to make the … 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 contains hemes, pigments responsible for the colour of red meat. The colour that meat takes is partly determined by the … See more Myoglobin belongs to the globin superfamily of proteins, and as with other globins, consists of eight alpha helices connected by loops. Myoglobin contains 153 amino acids. Myoglobin contains a porphyrin ring with an iron at its center. A … See more • Cytoglobin • Hemoglobin • Hemoprotein • Neuroglobin • Phytoglobin • Myoglobinuria - The presence of myoglobin in the urine See more 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 … 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 Many models of myoglobin have been synthesized as part of a broad interest in transition metal dioxygen complexes. A well known example is the picket fence porphyrin, which … See more firestone tires waterbury ct
