WebThese proteins are specialised in the binding of oxygen. Myoglobin is made up of 1 individual protein chain responsible for the transport and storage of oxygen in the muscles. Hemoglobin consists of 4 subunits (2 alpha globin chains and 2 beta globin chains) and is present in the blood to transport oxygen around the body. WebMar 15, 2024 · Myoglobin is an extremely compact protein with 75% alpha helical structure. It has 8 α−helices labeled A-H. Four are terminated by a proline, a helix breaker. The interior amino acids are almost entirely nonpolar. The only polar amino acids found completely buried are two histidines.
