She was the founding director of the Nebraska Redox Biology Center. Dr. Banerjee has published over one hundred articles and several book chapters, and edited The Chemistry and Biochemistry of Vitamin B-12. Klappentext Die erste Arbeit, die den Erkenntnisstand zum Vitamin B12 umfassend beschreibt! Angesprochen werden biologische, biochemische und chemische Problemkreise, beispielsweise zur Strukturchemie des Vitamins, zu Strukturbiologie und Reaktionsmechanismen der B12-abhängigen Enzyme und zur Rolle des Vitamins in der Ernährung und bei der Entstehung von Krankheiten. (09/99) Zusammenfassung There have been dramatic advances in the field of researching Vitamin B12, and those advances have served to revitalize interest in Vitamin B12 among biochemists, organic and inorganic chemists, microbiologists, structural biologists, and many other science professions.
