What is Myoglobin?

In skeletal muscle tissue, myoglobin is an iron and oxygen-binding protein present in red blood cells. It’s in charge of delivering oxygen to the working muscles. Seals and whales, for example, are able to stay underwater for longer periods of time because their muscles contain more myoglobin than other species.

It can be present in Type I muscle, Type II A muscle, and Type II B muscle, although it is most commonly found in the blood following a muscle injury.

Myoglobin was the first protein to have its three-dimensional structure revealed by X-ray crystallography which was discovered in 1958 by John Kendrew and associates.
