Myoglobin molecule. Computer model showing the structure of a myoglobin molecule. Myoglobin is a protein found in muscle tissue, where it binds to and stores oxygen to be used during strenuous exercise. The structure of the globin protein (blue) protects the haem (iron, red) group (centre) from being oxidised and destroyed by the oxygen it carries.
