Protein (17.5 kD) found in red skeletal muscle. The first protein for which the tertiary structure was determined by X-ray diffraction, by J.C. Kendrew's group working on sperm whale myoglobin. A single polypeptide chain of 153 amino acids, containing a haem group bonded via its ferric iron to two histidine residues, that binds oxygen non-cooperatively and has a higher affinity for oxygen than haemoglobin at all partial pressures. In capillaries oxygen is effectively removed from haemoglobin and diffuses into muscle fibres where it binds to myoglobin which acts as an oxygen store.
Myoglobin is an iron- and oxygen-binding protein found in the muscle tissue of vertebrates in general and in almost all mammals. It is related to hemoglobin, which is the iron- and oxygen-binding protein in blood, specifically in the red blood cells. Myoglobin is only found in the bloodstream after muscle injury. It is an abnormal finding, and can...Found on http://en.wikipedia.org/wiki/Myoglobin

(mi;uo-glo;bin) A molecule composed of globin protein and heme pigment.
