About this book

Vital life processes occur within the active sites of large biological macromolecules such as proteins, nucleic acids, and lipids. These nanodimensional structures greatly accelerate biological reactions. The chirality of the reactants also has a strong influence on the process, but its importance in such biological reactions has only recently begun to be understood.

This book explores the influence of chirality on reaction mechanisms in such biological nanospaces. The text addresses the influence of the chirality of amino acid and sugar in the active sites of transferase, oxidoreductases, hydrolases, lysases, isomerase, ligases, and other systems. It also covers ribosomal architecture.

Biography

Nilashis Nandi was born in Cooch Behar, West Bengal, India (1965). He received his B.Sc. (Hons.) (1983) and M.Sc. (1985) degrees from North Bengal University and Ph.D. (1992) from Visva Bharati University. He became a postdoctoral fellow at the Indian Institute of Science, India (1993--1997), a J.S.P.S. postdoctoral fellow at Nagoya University, Japan (1997--1999), and an Alexander von Humboldt postdoctoral fellow at the Max Planck Institute of Colloids and Interfaces, Germany (1999--2000). Dr. Nandi was a faculty member in the chemistry group of Birla Institute of Technology and Science, Pilani, India from 2001--2007 and became a professor in the Department of Chemistry, University of Kalyani in 2008 where he has worked ever since. His research interest is focused on theoretical and computational studies in biophysical chemistry.
