Coboglobin

A coboglobin is a synthetic compound, a metalloprotein chemically similar to hemoglobin or myoglobin but using the metal cobalt instead of iron (hence the name). Just like hemoglobin and myoglobin, the coboglobins are able to reversably bind molecular oxygen (O2) at the metal atom. However they lose this ability much faster than the natural molecules.
