Introduction to Modern Biochemistry, Fourth Edition provides an understanding of the chemical background of biological phenomena. This book discusses the concepts of generation and utilization of free energy. Organized into 23 chapters, this edition starts with an overview of the important role of amides in biochemistry. This text then explores the chemical structure of proteins and describes the methods of determining the amino acids sequence of proteins. Other chapters consider the role of genes in protein and enzyme synthesis. This book discusses as well the significance of the submicroscopic structure of the cell in biochemical reactions. The reader is also introduced to the chemistry of the carbohydrates. The final chapter deals with biochemical functions of various organs, including the digestive tract, liver, kidney, nervous system, muscles, and connective tissues. This book is a valuable resource for biologists, biochemists, scientists, researchers, and readers who are interested in the field of biochemistry.

Introduction to Modern Biochemistry, Fourth Edition provides a better understanding of the chemical background of biological phenomena. The book presents an introduction and a survey of the facts and concepts of biochemistry. The text is intended to be an instructional material. Topics of general importance, such as the generation and utilization of free energy, the role of genes in protein and enzyme synthesis, and the importance of the submicroscopic structure of the cell in biochemical reactions, are emphasized. No distinction between descriptive biochemistry and dynamic biochemistry are made, for the sake of simplicity and better comprehension of concepts presented in the book. Students, biochemists, biologists, pharmacists, and medical practitioners will find this book as a good reference.

Mechanisms of Hormone Action: A NATO Advanced Study Institute focuses on the action mechanisms of hormones, including regulation of proteins, hormone actions, and biosynthesis. The selection first offers information on hormone action at the cell membrane and a new approach to the structure of polypeptides and proteins in biological systems, such as the membranes of cells. Discussions focus on the cell membrane as a possible locus for the hormone receptor; gaps in understanding of the molecular organization of the cell membrane; and a possible model of hormone action at the membrane level. The text also ponders on insulin and regulation of protein biosynthesis, including insulin and protein biosynthesis, insulin and nucleic acid metabolism, and proposal as to the mode of action of insulin in stimulating protein synthesis. The publication elaborates on the action of a neurohypophysial hormone in an elasmobranch fish; the effect of ecdysone on gene activity patterns in giant chromosomes; and action of ecdysone on RNA and protein metabolism in the blowfly, Calliphora erythrocephala. Topics include nature of the enzyme induction, ecdysone and RNA metabolism, and nature of the epidermis nuclear RNA fractions isolated by the Georgiev method. The selection is a valuable reference for readers interested in the mechanisms of hormone action.

Introduction to Modern Biochemistry, Second Edition focuses on the methodologies, processes, reactions, and technologies involved in biochemistry. The publication first takes a look at organic chemistry and biochemistry, amino acids, and peptides. Discussions focus on the determination of amino acid sequence in peptides, naturally occurring peptides, chemical properties, separation of amino acids, hydrocarbons as parent substances, functional groups, polymeric compounds, and reactions with biochemical significance. The text then ponders on proteins, enzymes and biocatalysis, and coenzymes. The manuscript examines nucleic acids and protein biosynthesis, metabolism of proteins, and porphyrins and hemins. Topics include chemical constitution of heme, significance and reactions of blood pigment, metabolism of aromatic amino acids, degradation to activated fatty acids, decarboxylation of amino acids, and biosynthesis and degradation of nucleotides. The text also ponders on carbon dioxide formation in the citrate cycle, fats and fat metabolism, and phosphatides, cerebrosides, and gangliosides. The book is a valuable reference for biochemists and researchers interested in the processes, approaches, and technologies involved in biochemistry.

This volume represents the proceedings of the 24th Mos­ bach Colloquium on "Regulation of Transcription and Trans­ lation in Eukaryotes" which was held April 26-28, 1973, in Mosbach, Germany, under the auspices of the Gesellschaft fiir Biologische Chemie. To the three of us (H. KERSTEN, P. KARLSON and myself) who were commissioned with the invitation of speakers, it was a difficult decision as to whether we should attempt to cover with some twenty contributions as many aspects of this broad topic as possible, or to sacrifice the intellectually perhaps more pleasing but more specula­ tive concepts and to concentrate on a few aspects of gene expression in reasonable detail. We unanimously decided on the latter course, leaving such important and timely topics as for example, hormone action, cyclic AMP and reverse transcription to the proceedings of other symposia, and con­ centrating on the four questions which are most basic to an understanding of the mechanisms of transcription and trans­ lation and for which fragmentary but nonetheless reliable experimental results have become available within the last few years. These are the structure of chromatin, the syn­ thesis of messenger RNA, the structure of the active ribo­ some, and the role of initiation factors in protein synthesis.

It is about 15 years since the first presentation on uteroglobin was given to a group of developmental biologists, reproductive physiologists, and geneticists who had gathered in November 1966 at Konstanz (Germany). In the following decade so much knowledge was accumulated that a special symposium seemed appropriate. This was organized as a satellite symposium to the International Congress of Endocrinology at Hamburg and brought together 50 scientists at Aachen. These scientists, working in the field of pro­ teins and steroids, in early pregnancy, recognized the impact of what had been reported, and many of them later agreed to contribute to this booN. and thus to present their research d,!ta available until December 1980. The present volume covers a relatively broad spectrum of data and observations which shed some light on preimplantational embryonic life and on the supports and obstacles provided by the maternal organism with respect to final accomplishment of normal im­ plantation and establishment of pregnancy. The book will serve both as a textbook and as a scientific dictionary for Ph.D. students, postdoctoral fellows and advanced scientists working in this area. The course of early pregnancy depends very much on a proper balance of steroid hor­ mones, and the induction of protein synthesis by steroid hormones is one of the well­ known fundamental processes in cellular differentiation and embryonic development.
