Myoglobin - Wikipedia
WEBMyoglobin is an oxygen-binding protein located primarily in muscles. Myoglobin serves as a local oxygen reservoir that can temporarily provide oxygen when blood oxygen delivery is insufficient during periods of intense muscular activity. Iron within the heme group must be in the Fe+2 state to bind oxygen.
Myoglobin: What It Is, Function, Test & Results - Cleveland Clinic
WEBMyoglobin is a protein that’s found in your striated muscles, which includes skeletal muscles (the muscles attached to your bones and tendons) and heart muscles. Its main function is to supply oxygen to the cells in your muscles (myocytes). All cells in your body need oxygen in order to function. They use oxygen to convert stored energy.

WEBMyoglobin (Mb) is a heme-containing globular protein that is found in abundance in myocyte cells of heart and skeletal muscle. Mb and Mb-like proteins are also found in many taxa, including bacteria, plants, fungi, and animals.
Myoglobin - Physiopedia
WEBMyoglobin (Mb) is an iron -containing heme protein that is present predominantly in the sarcoplasm of skeletal and cardiac muscle s. 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.
Myoglobin (Blood) - Health Encyclopedia - University of Rochester ...
WEBMyoglobin is found in your heart and skeletal muscles. There it captures oxygen that muscle cells use for energy. When you have a heart attack or severe muscle damage, myoglobin is released into your blood. Myoglobin increases in your blood 2 to 3 hours after the first symptoms of muscle damage. It usually peaks about 8 to 12 hours later.
