WebJan 25, 2024 · Myoglobin (Mb) is a globular protein in skeletal muscle that plays an essential role in aerobic metabolism or energy production. The function of Mb has long remained largely unknown until recently, and it is one of the muscle tissue proteins. Researchers at Harvard Medical School discovered that Mb carries oxygen from … WebOxygen transport proteins, such as hemoglobin and myoglobin, are essential for the delivery of oxygen to cells, as they are able to bind to oxygen and carry it to the cells that need it. Hemoglobin is an oxygen transport protein that is found in red blood cells. It is composed of four subunits, each of which can bind to a single oxygen molecule. WebOxygen solubility in aqueous solution is low. <10-4 M, an insufficient concentration for metabolic needs.
