This classic Chemistry of Enzymes has been compilated to provide an understanding of enzymology for university degree study and teaching. It comprehensively covers theory and applications of these biological life supporting catalysts in a readable book that will serve as a bridge to more advanced and specialized areas. It not only introduces the fundamentals and biochemistry of enzymes but also provides the molecular and experimental background. This unique piece of work compiled five volumes containing wealth of information for researchers, microbiologists, and biotechnologists. This excellent title is intended mainly for students taking degree course which have a substantial biochemistry component. The chief aim of this particular book is to help student understand the concepts involved in enzymology. An attempt has been made to give a perspective of each topic, and examples are quoted where appropriate.
