Looking at enzymes from an organic chemistry perspective, this updated reference includes information on recent advances in our understanding of enzyme action; topical examples to illustrate key points; two-color figures of the active sites of enzymes discussed in the text to illustrate the interplay between enzyme structure and function; and end-of-chapter problems to allow readers to check their understanding of the material. This concise but comprehensive guide is essential for undergraduate and postgraduate students of organic, bio-organic, and medicinal chemistry, chemical biology, bioche.
