Myoglobin - Definition

Definition


Myoglobin is a protein which mainly serves to carry oxygen to the muscles in order for them to function correctly. It has a similar structure to that of hemoglobin, which transports oxygen in the bloodstream. Myoglobin is also considered to be a pigment, as it is the reason that muscles are red. Usually contained in the muscles, myoglobin can be released into the bloodstream following a serious muscular lesion, notably in cases of myocardial infarction, and has even been found in urine in certain cases. Myoglobin quantities in the blood or urine can therefore help towards diagnosing various diseases or conditions.
