Introduction[edit | edit source]
Myoglobin (Hb) is an iron-containing heme protein that is present predominantly in the sarcoplasm of skeletal and cardiac muscles. Due to the presence of heme moiety, myoglobin serves as a carrier and store for oxygen in muscle cells of the body. Myoglobin has more affinity for oxygen as compared to hemoglobin. As a result, it can acquire oxygen from hemoglobin, hence transferring it from the blood to the muscle tissues.[1]

Here is the basic information Mb.
- It is a low molecular weight oxygen-binding heme protein and is one of the most important proteins in the human body.
- It acts as an oxygen reservoir unit, suppling oxygen to working muscles.
- It is mainly found in the heart and skeletal muscle cells, occurring in the highest concentration in the striated muscles of vertebrates.
- In skeletal muscle it serves to transport oxygen from the cell membrane to the mitochondria.
- Diving mammals such as seals and whales are able to remain submerged for long periods because they have greater amounts of myoglobin in their muscles than other animals do[2].
