Bioinorganic chemistry is the science that studies the role of metals in biology. This field involves the study of the behavior of metalloproteins and artificially introduced metals in medicine and toxicology. Some of the focus areas in bioinorganic chemistry are the study of transport and storage of metal ions, enzymology, bioorganometallic chemistry, toxicity, oxygen transport and activation proteins, metals in medicine, etc. Many reactions involve water and metal ions that are usually at the catalytic centers for these enzymes. Aerobic life has an extensive use of metals like copper, iron and manganese. Heme is used in the form of hemoglobin by red blood cells for the transport of oxygen. Some metalloproteins protect biological systems from the potentially harmful effects of reactive oxygen-containing molecules. This book aims to shed light on some of the unexplored aspects of bioinorganic chemistry and the recent researches in this field. It elucidates new techniques and their applications in a multidisciplinary manner. Researchers and students in this field will be assisted by this book.
