Heinz bodies are formed by damage to the hemoglobin component molecules, usually through oxidative damage by administered drugs, or from an inherited mutation (i.e. change of an internal amino acid residue). As a result, an electron from the hemoglobin is transferred to an oxygen molecule, which creates a reactive oxygen species (ROS) that can cause severe cell damage leading to premature cell lysis.
