Chemistry And Biochemistry Of B12

A Definitive New Reference for the Latest Advances in B_12 Chemistry and Biochemistry Over the past decade, the field of B_12 research has been revolutionized by such major breakthroughs as the unraveling of the entire biosynthetic pathway for this important vitamin. This comprehensive compendium surveys the wealth of information that has accumulated, covering in one volume virtually all aspects of the field-from physical and inorganic chemistry to enzymology, microbiology, medicine, and diagnostic and therapeutic applications. Edited by Dr. Ruma Banerjee, a highly respected and active member of the B_12 community, this work provides B_12 researchers with a dependable and up-to-date reference on the subject. Leading authorities from five continents explore such new areas as the structural biology of B_12-dependent enzymes, free-radical-mediated reaction mechanisms, biosynthesis, and much more. The role of B_12 in nutrition and disease, and B_12 transport, are also thoroughly examined. Complete with color illustrations and extensive references, Chemistry and Biochemistry of B_12 is a one-of-a-kind resource for biochemists, biophysicists, spectroscopists, microbiologists, molecular biologists, and anyone with an interest in "nature's most beautiful cofactor."
