myoglobin

 [mi´o-glo″bin]
the oxygen-transporting pigment of muscle, a type of hemoprotein resembling a single subunit of hemoglobin, being composed of one globin polypeptide chain and one heme group.

my·o·glo·bin (Mb, MbCO, MbO2),

(mī'ō-glō'bin), [MIM*160000]
The oxygen-carrying and storage protein of muscle, resembling hemoglobin but containing only one subunit and one heme as part of the molecule (rather than the four of hemoglobin), and with a molecular weight approximately one quarter that of hemoglobin.
[myo- + hemoglobin]

myoglobin

(mī′ə-glō′bĭn)
n.
A single-chain, iron-containing protein found in muscle fibers, structurally similar to a single subunit of hemoglobin and having a higher affinity for oxygen than hemoglobin of the blood.

my·o·glo·bin

(mī'ō-glō'bin)
The oxygen-transporting and storage protein of muscle, resembling blood hemoglobin in function but with a molecular weight approximately one quarter that of hemoglobin. Serum levels of this protein are often measured to facilitate diagnosis of an acute myocardial infarction; it is released into the circulation within 2-4 hours after myocardial infarction, peaks at about 8-12 hours, and returns to normal after 18-24 hours.

Synonym(s): muscle hemoglobin.

myoglobin

The muscle cell equivalent of the haemoglobin of the blood. Myoglobin acts as a temporary oxygen store from which oxygen is drawn as the muscle requires it.

myoglobin

a relatively small globular protein (MW = 17 000) consisting of 153 amino acids in a POLYPEPTIDE CHAIN and one HAEM group. The molecule is found in the muscles of vertebrates and some invertebrates (giving the muscles a red colour) and has a high affinity for oxygen.

Myoglobin

A protein that holds oxygen in heart and skeletal muscle. It rises after damage to either of these muscle types.
