Inorganic biochemistry is an emerging subject and interdisciplinary field between inorganic chemistry and biochemistry. The task of inorganic biochemistry is to research the interaction between the metal complex (or metal ion) with biological ligand at the molecular level. There exists wide research about inorganic biochemistry such as biological macromolecular, oxygen carrier, hemoglobin, mimic enzyme, DNA-binding and cytotoxicity, biological mineralization, etc.
