Biochemical Catalysts In Life

Excerpt from Biochemical Catalysts in Life and Industry: Proteolytic Enzymes All, so far as Chemistry yet permits us to say, have composi tions similar to those of the albuminoids. However, they are accompanied by mineral matter whose presence has been recog nized, in certain cases, as being useful, or even necessary as, for example, manganese in the process of oxidation, or calcium in the coagulation of blood so that one ends by asking if the rcle of these substances, in vital manifestations in general, is not even a greater one than has hitherto been supposed. The constant presence of iron in the hemoglobin, of magnesium in the chloro phyll, or of iodine in the thyroids, is perhaps an indication of unknown catalytic action, which would thus explain the physi ological importance of these substances, from the points of View of respiration, the assimilation of carbon dioxide and the normal functioning of the organism, respectively. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at www.forgottenbooks.com This book is a reproduction of an important historical work. Forgotten Books uses state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in our edition. We do, however, repair the vast majority of imperfections successfully; any imperfections that remain are intentionally left to preserve the state of such historical works.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The contents of this book cover: 'Biochemistry: Catalysts of Life: Enzymes: The Catalysts of Life', 'Enzyme is a Biological Catalyst', 'Structures and Mechanisms', 'Cofactors and Coenzymes', 'Reversible Inhibitors', and much more.

The aim of the book is to introduce the reader to the kinetic analysis of a wide range of biological processes at the molecular level. It is intended to show that the same approach can be used to resolve the number of steps in enzyme reactions, muscle contraction, visual perception and ligand binding receptors that trigger other physiological processes. Attention is also given to methods for characterizing these steps in chemical terms. Although the treatment is mainly theoretical, a wide range of examples and experimental techniques are also introduced and an historical approach is used to demonstrate the development of the theory and experimental techniques of kinetic analysis in biology.

The application of enzymes or whole cells (fermentatively active or resting; microbial, plant, or animal) to carry out selective transformations of commercial importance is the central theme of industrial biocatalysis. Traditionally, biocatalysis has been in the domain of the life scientist or biochemical engineer. However, recent advances in this field have enabled biocatalytic processes to compete head on with, and in some cases out perform, conventional chemical processing. Chemo-biocatalytic systems are being developed thereby combining the most attractive features of bio catalysts, namely high specificity, with those of chemical catalysts, such as high reactivities and wide substrate specificities. Hence, synthetic chemists and chemical engineers are now beginning to use biocatalysts as highly selective reagents in chemical synthesis and processing. This book is about biocatalysts and their past, present, and potential applications in the food, pharmaceutical, and chemical industries. The con cept of the book did not emanate from a meeting. Rather, it is a compila tion of selected examples where biocatalysis either has already made a significant impact in the aforementioned industries, or has the potential to make a substantial contribution. I have been fortunate to have assembled contributions from world-class researchers in the field of biocatalysis. Their timely contributions are sincerely appreciated.
