Abstract: Free divers can’t hold their breath as long as whales, but they train their bodies to maximize their oxygen (O2) storing potential using the protein myoglobin. Myoglobin’s structure has been known for decades, but researchers are still trying to determine just how myoglobin functions. Found in muscle tissue, myoglobin stores O2, a molecule needed to produce chemical energy. Toxic ligands, such as carbon monoxide (CO) and cyanide, also bind to myoglobin. When CO binds to a free heme group, the heme's binding af… Show more
