myoglobin
[mī′ōglō′bin]
Etymology: Gk, mys + L, globus, ball
a ferrous globin complex consisting of one heme molecule containing one iron molecule attached to a single globin chain. Myoglobin is responsible for the red color of muscle and for its ability to store oxygen. Normal blood levels of myoglobin are 0 to 85 ng/mL. Excessive myoglobin levels may result from massive burns or trauma.
myoglobin (mīˑ·ō·glōˈ·bin),
n oxygen- and iron-carrying compound in muscles.
myoglobin
the oxygen-transporting pigment of muscle, a conjugated protein resembling a single subunit of hemoglobin, being composed of one globin polypeptide chain and one heme group.
