WebMyoglobin is a low molecular weight oxygen binding heme protein that is found exclusively in heart and skeletal muscle cells. Myoglobin constitutes up to 5–10% of all the … WebMyoglobin contains 8 variously sized right-handed helical regions, joined by non-ordered or random coil regions. [ 3] Myoglobin is critical to skeletal muscle O 2 supply at near-maximum oxygen demand, and prevents anoxia by maintaining PO 2 above levels needed to support mitochondrial function.

Besides troponin, myoglobin determination in serum may play a con-tributing step in the diagnosis of myocardial ischaemia particularly acute myocardial infarction.1, 2 Elevated myoglobin values can also occur after skeletal muscle
WebOct 1, 2000 · The role of myoglobin as an oxygen store is well established. In terrestrial mammals, it compensates for the disadvantage of a reduced blood flow in heart and skeletal muscle during contraction. In aquatic mammals, which are characterized by markedly higher myoglobin concentrations than terrestrial mammals, it serves as an … Webmyoglobin, a protein found in the muscle cells of animals. It functions as an oxygen-storage unit, providing oxygen to the working muscles. Diving mammals such as seals and whales are able to remain submerged for long periods because they have greater amounts of myoglobin in their muscles than other animals do. There is a close chemical similarity …
