Biochemistry Of Smooth Muscle Contraction

By Michael Bárány

Biochemistry of Smooth Muscle Contraction PDF provides a systematic account of the biochemistry of smooth muscle contraction. As a comprehensive guide to this rapidly growing area of research, it covers the structure and characteristic properties of contractile and regulatory proteins, with special emphasis on their predicted function in the live muscle. Also included in this book are intermediate filament proteins, and desmin and vimentin, whose function in smooth muscle is unknown; and several enzymes involved in the phosphorylation-dephosphorylation of contractile and other proteins.

Biochemistry Of Selenium By Raymond Shamberger

By Raymond Shamberger

In recent years many exciting research results have indicated that selen- ium, depending on its concentration, can influence mammalian metabo- lism. It has been estimated that in selenium-deficient areas, selenium or selenium-vitamin E combinations added to animal feed can prevent an- nuallosses to beef and dairy cattle and sheep valued at 545 million dollars and poultry and swine losses valued at 82 million dollars. Some animal diseases that can be prevented by a selenium-supple- mented diet include liver necrosis, nutritional muscular dystrophy, exu- dative diathesis, pancreatic degeneration, mulberry heart disease, infer- tility, growth impairment, periodontal disease, and encephalomalacia. Selenium intake levels are dependent on the plant or animal feed con- centrations, which, in turn, are dependent on the pH of the soil and the types of rocks from which the soils are derived. At normal metabolic levels selenium possesses an antioxidant affect manifested through glutathione peroxidase, and selenium also has an ef- fect on cytochrome P-450 and heme metabolism. Comparisons are made between metabolism of selenium and sulfur in plants, animals, and hu- mans. At greater selenium intake levels acute poisoning occurs when high-selenium-content (10,000 ppm Se) plants are consumed in large quan- tities. The toxic reactions were first manifested in cavalry horses near Fort Randall, Nebraska, in the 1860s.

Biochemistry of Microbial Degradation

Biochemistry of microbial degradation

Biochemistry Of Microbial Degradation

By Colin Ratledge

Biochemistry of Microbial Degradation Book PDF. Life on the planet depends on microbial activity. The recycling of carbon, nitrogen, sulphur, oxygen, phosphate and all the other elements that constitute living matter are continuously in flux: microorganisms participate in key steps in these processes and without them life would cease within a few short years. The comparatively recent advent of man-made chemicals has now challenged the environment: where degradation does not occur, accumulation must perforce take place. Surprisingly though, even the most recalcitrant of molecules are gradually broken down and very few materials are truly impervious to microbial attack. Microorganisms, by their rapid growth rates, have the most rapid turn-over of their DNA of all living cells. Consequently they can evolve altered genes and therefore produce novel enzymes for handling “foreign” compounds – the xenobiotics – in a manner not seen with such effect in other organisms. Evolution, with the production of micro-organisms able to degrade molecules hitherto intractable to breakdown, is therefore a continuing event. Now, through the agency of genetic manipulation, it is possible to accelerate this process of natural evolution in a very directed manner. The time-scale before a new microorganism emerges that can utilize a recalcitrant molecule has now been considerably shortened by the application of well-understood genetic principles into microbiology. However, before these principles can be successfully used, it is essential that we understand the mechanism by which molecules are degraded, otherwise we shall not know where best to direct these efforts.

Biochemistry of Lipids, Lipoproteins and Membranes 5th Edition

Biochemistry of Lipids, Lipoproteins and Membranes, 5th Edition

Biochemistry Of Lipids, Lipoproteins And Membranes, 5Th Edition

By Neale Ridgway and Roger McLeod

Biochemistry of Lipids, Lipoproteins and Membranes, 5th Edition PDF. Research on the biochemistry and molecular biology of lipids and lipoproteins has experienced remarkable growth in the past 20 years, particularly with the realization that many different classes of lipids play fundamental roles in diseases such as heart disease, obesity, diabetes, cancer and neurodegenerative disorders. The 5th edition of this book has been written with two major objectives. The first objective is to provide students and teachers with an advanced up-to-date textbook covering the major areas of current interest in the lipid field. The chapters are written for students and researchers familiar with the general concepts of lipid metabolism but who wish to expand their knowledge in this area. The second objective is to provide a text for scientists who are about to enter the field of lipids, lipoproteins and membranes and who wish to learn more about this area of research. All of the chapters have been extensively updated since the 4th edition appeared in 2002.

  • Represents a bridge between the superficial coverage of the lipid field found in basic biochemistry text books and the highly specialized material contained in scientific review articles and monographs
  • Allows scientists to become familiar with recent developments related to their own research interests, and will help clinical researchers and medical students keep abreast of developments in basic science that are important for subsequent clinical advances
  • Serves as a general reference book for scientists studying lipids, lipoproteins and membranes and as an advanced and up-to-date textbook for teachers and students who are familiar with the basic concepts of lipid biochemistry

Biochemistry and Structure of Cell Organelles

Biochemistry and Structure of Cell Organelles PDF

Biochemistry and Structure of Cell Organelles

Biochemistry And Structure Of Cell Organelles

By Robert A Reid

Biochemistry and Structure of Cell Organelles PDF is an up-to-date compact book on cell organelles that transmits the excitement and challenge of modern subcellular biology. We hope that the book will be interesting and useful to students of the biological sciences and medicine, and to those in the teaching professions who do not have ready access to research papers. Since space is at a premium, we have denied ourselves the luxury of a philosophical discussion of the problems of defining organelles. Rather we have chosen to include all those intracellular structures which have limiting membranes and definable compartments. The separate chapters consider nuclei, plastids, mitochondria, microbodies, endoplasmic and sarcoplasmic reticulum, Golgi bodies, lysosomes and various secretory vesicles, including chromaffin granules and synaptic vesicles. Nucleoli, ribosomes, and centrioles are included in the chapter on nuclei. New and exciting information about all these structures has emerged in recent years-for example, the nucleosome, interrupted genes, signal sequences on proteins destined for the bioenergetic organelles, mapping and sequencing of organelle genes, and consolidation of chemiosmosis as a unifying principle in energy transduction. We have outlined as many of these developments as possible and pointed out some areas of controversy. The literature on subcellular biology is so extensive that it would have been easier to have written a separate book on each organelle.

Biochemistry and Physiology of the Neutrophil

Biochemistry And Physiology Of The Neutrophil

By Steven W. Edwards

Biochemistry and Physiology of the Neutrophil PDF describes the role of the neutrophil in infection and inflammation and provides an up-to-date review of the biochemistry and physiology of these cells, highlighting the mechanisms by which they seek out and destroy pathogenic micro-organisms. The development of these cells during haematopoiesis is described and the mechanisms which lead to the production of reactive oxidants and the intracellular signal transduction systems which lead to the cell’s activation are reviewed. The book also discusses recent discoveries concerning the role of cytokines in the regulation of neutrophil function together with the importance of the neutrophil as a generator of inflammatory cytokines. Finally there is a description of the biochemical defects that give rise to some of the neutrophil-associated human diseases.
