This volume grew out of a symposium organized by the students of Professor Myron L. Bender. His research focused on the mechanisms of enzymatic catalysis and was instrumental in showing that enzymes do not possess magical powers to accelerate reactions a trillion times on an average, but follow simple rules of chemistry. A group of scientists who were trained by Bender have contributed some of their work to this book to pay homage to their mentor. The range of topics covered is such that researchers and industry with interest in biological chemistry will gain knowledge from the advances being made in related fields. The book shows organic chemists what advances have taken place in biological chemistry and biochemists will discover how principles of organic chemistry can be applied to reveal the powers of enzymatic catalysis.
