This enzymology textbook for graduate and advanced undergraduate students covers the syllabi of most universities where this subject is regularly taught. It focuses on the synchrony between the two broad mechanistic facets of enzymology: the chemical and the kinetic, and also highlights the synergy between enzyme structure and mechanism. Designed for self-study, it explains how to plan enzyme experiments and subsequently analyze the data collected. The book is divided into five major sections: 1] Introduction to enzymes, 2] Practical aspects, 3] Kinetic Mechanisms, 4] Chemical Mechanisms, and 5] Enzymology Frontiers. Individual concepts are treated as stand-alone chapters; readers can explore any single concept with minimal cross-referencing to the rest of the book. Further, complex approaches requiring specialized techniques and involved experimentation (beyond the reach of an average laboratory) are covered in theory with suitable references to guide readers. The book provides students, researchers and academics in the broad area of biology with a sound theoretical and practical knowledge of enzymes. It also caters to those who do not have a practicing enzymologist to teach them the subject.

The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.

This book describes the fundamental concepts, the latest developments and the outlook of the field of nanozymes (i.e., the catalytic nanomaterials with enzymatic characteristics). As one of today’s most exciting fields, nanozyme research lies at the interface of chemistry, biology, materials science and nanotechnology. Each of the book’s six chapters explores advances in nanozymes. Following an introduction to the rise of nanozymes research in the course of research on natural enzymes and artificial enzymes in Chapter 1, Chapters 2 through 5 discuss different nanomaterials used to mimic various natural enzymes, from carbon-based and metal-based nanomaterials to metal oxide-based nanomaterials and other nanomaterials. In each of these chapters, the nanomaterials’ enzyme mimetic activities, catalytic mechanisms and key applications are covered. In closing, Chapter 6 addresses the current challenges and outlines further directions for nanozymes. Presenting extensive information on nanozymes and supplemented with a wealth of color illustrations and tables, the book offers an ideal guide for readers from disparate areas, including analytical chemistry, materials science, nanoscience and nanotechnology, biomedical and clinical engineering, environmental science and engineering, green chemistry, and novel catalysis.

The synthesis of catalytically active polymers by MIP techniques results in tailor-made synthetic polymers, which are capable of subsequent molecular recognition of particular molecules. Even though considerable efforts have been expanded in the past to produce effective enzyme mimetic MIPs, catalytic rates and specificities have still been significantly lower, when compared to natural enzymes. The main reasons have been the use of unsuitable templates (i.e. those lacking particular molecular geometrics or stereochemistries) and suboptimal orientation of the appropriate active sites in the polymer matrix. Since the catalytic activity of a MIP is mediated through the cavity sites created in the macromolecular entity of the MIP, the generation of these active sites should be achieved through a particular polymerisation chemistry and utilising specific templates. Since control over the molecular architecture of the cavity sites in the MIPs is the decisive factors for those polymers to exhibit efficient catalytic activity and selectivity, templates that feature the appropriate functional and geometrical specification have to be designed and synthesised. A significant approach for successful achievement of this therefore should use the catalytic mechanism of the enzymes as a guideline. It has been described that the catalytic rate of biological and chemical reactions by enzymes is achieved when enzymes lower the activation energy of the reaction. This is achieved due to the differential binding energy of the substrate in its transition state (TS) and its ground state (GS). In this case, the higher binding affinity of the enzyme to the TS of the substrate compared to its GS enables the activation energy of the reaction to be lowered, and hence enhances the rate of the reaction.
