Metal Ions in Biological Systems is devoted to increasing our understanding of the relationship between the chemistry of metals and life processes. The volumes reflect the interdisciplinary nature of bioinorganic chemistry and coordinate the efforts of researchers in the fields of biochemistry, inorganic chemistry, coordination chemistry, environmental chemistry, biophysics, pharmacy, and medicine. Volumes deal with such topics as the formation, stability, structure, and reactivity of biological compounds of low and high molecular weight containing metal ions; the metabolism and transport of metal ions and their complexes; and new models of complicated natural structures and processes. Volume 21 describes the underlying theories of nuclear magnetic resonance (NMR), promoting a wider use of NMR in studies of paramagnetic species. In six concise chapters by leading international authorities, Applications of Nuclear Magnetic Resonance to Paramagnetic Species outlines the most recent developments regarding the use of nuclear relaxation as a source for structural information ... examines studies of magnetically coupled metalloproteins and metal-porphyrin induced dipolar shifts for conformational analysis ... and evaluates the potential of paramagnetic ions as agents for enhancing NMR image contrast. With over 500 references that facilitate further research, Applications of Nuclear Magnetic Resonance to Paramagnetic Species is an essential resource for scientists and students in such disciplines as biophysics; bioinorganic, inorganic, and coordination chemistry; biochemistry; molecular biology; and enzymology.
