Myoglobin and iron
WebEach of the four chains is associated with an iron or heme group which binds with one oxygen molecule each. What is Myoglobin? Myoglobin is a globular protein found in the muscles which are responsible for the storage of oxygen in the muscle cells. This stored oxygen is later used up by us while doing different activities. WebMyoglobin is a cytoplasmic hemoprotein, expressed solely in cardiac myocytes and oxidative skeletal muscle fibers, that reversibly binds O2 by its heme residue, a porphyrin …
