The more advanced chemical and biochemical aspects and methods are all developed during the course. The course will provide students with a general overview of the many very fundamental tasks performed by inorganic elements in living organisms as well as the related methods and theories with particular emphasis on enzymatic conversions and electron transfer. This goes along with the elucidation of model systems and technical applications of both, concepts learned from nature as well as biological systems. . Interdisciplinary research on the inorganic chemistry of life has developed into a major source of innovation for catalyst development, material chemistry and medicine. The course "Biological Inorganic Chemistry" details the numerous functions of inorganic materials and ions in biology. It provides a general overview of the fundamental tasks performed by inorganic elements in living organisms as well as the related methods and theories with particular emphasis on enzymatic conversions, inorganic biomaterials and medical applications. Nature’s strategies are elucidated based on model systems and basic concepts are illustrated by examples relevant to technological or medical applications. The course is designed for P.h.D students in chemistry, biochemistry and biotechnology, yet interested students on the M.Sc. level are welcome.
