Available in PDF, EPUB and Kindle. Book excerpt: Amino acids are featured in course syllabuses and in project and research work over a wide spectrum of subject areas in chemistry and biology. Chemists and biochemists using amino acids have many common needs when they turn to the literature for comprehensive information. Among these common interests, analytical studies, in particular, have undergone rapid development in recent years. All other chemical and biochemical aspects of amino acids - synthesis, properties and reactions, preparation of derivatives for use in peptide synthesis, racemization and other fundamental mechanistic knowledge - have been the subject of vigorous progress. This book offers a thorough treatment of all these developing areas, and is structured in the belief that biochemists, physiologists and others will profit from access to information on topics such as the physical chemistry of amino acid solutions, as well as from thorough coverage of amino acid metabolism, biosynthesis and enzyme inhibition; and that chemists will find relevant material in biological areas as well as in the analysis, synthesis and reactions of amino acids.

Download or read book Amino Acid Analysis Protocols written by Catherine Cooper and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of classic and cutting-edge techniques of high utility in answering specific biological questions about amino acids. Common methods include those based on HPLC or gas chromatography separation and analysis after precolumn derivatization. New techniques based on capillary electrophoresis separation, high-performance anion exchange chromatography, and mass spectrometry are also presented. Each method is described in step-by-step detail to ensure successful experimental results and emphasizes sample preparation, particularly the collection and storage of bodily fluids. Up-to-date and highly practical, Amino Acid Analysis Protocols offers analytical and clinical chemists, as well as a broad range of biological and biomedical investigators, a rich compendium of laboratory tools for the productive analysis of both common and uncommon amino acids.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Members of the radical S-adenosyl-L-methionine (SAM) family of enzymes catalyze reactions that would normally be biologically impossible by utilizing SAM as a source of a primary radical. Many of the reactions catalyzed by these enzymes change the traditional paradigms for biological chemistry. The putative radical SAM enzymes PhpK and PylB both catalyze unusual amino acid modifications that have remained largely uncharacterized over the past 20 years. PhpK catalyzes methyl transfer to an electrophilic phosphinate, completing the only known naturally-occurring carbon-phosphorus-carbon linkage. We developed methodology to isolate, purify, and begin in vitro characterization of PhpK. We found PhpK was methylcobalamin-dependent, transferring the methyl group from methylcobalamin directly to the final product. The enzyme used a CxxxCxxC bound four-iron, four-sulfur cluster together with SAM to catalyze P-methylation, consistent with known radical SAM mechanisms. PylB catalyzes the first step in the biosynthesis of the 22nd genetically-encoded amino acid pyrrolysine. It performs a lysine isomerization to form 3-methyl-D-ornithine. Since the protons at C-4 have a pKa~50, the reaction is undoubtedly catalyzed by a radical mechanism. We have begun developing methods for purification and assays of PylB to study the mechanistic details of this reaction. These studies set the stage for characterization of these radical SAM enzymes and future engineering efforts towards industrial/commercial applications for the reactions they catalyze.

Download or read book Encyclopedia of Scientific Dating Methods written by W. Jack Rink and published by Springer. This book was released on 2015-08-15 with total page 978 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an overview of (1) the physical and chemical foundations of dating methods and (2) the applications of dating methods in the geological sciences, biology, and archaeology, in almost 200 articles from over 200 international authors. It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields. No other volume has a similar scope, in terms of methods and applications and particularly time range. Dating methods are used to determine the timing and rate of various processes, such as sedimentation (terrestrial and marine), tectonics, volcanism, geomorphological change, cooling rates, crystallization, fluid flow, glaciation, climate change and evolution. The volume includes applications in terrestrial and extraterrestrial settings, the burgeoning field of molecular-clock dating and topics in the intersection of earth sciences with forensics. The content covers a broad range of techniques and applications. All major accepted dating techniques are included, as well as all major datable materials.

Download or read book A Consumer s Guide to Archaeological Science written by Mary E. Malainey and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many archaeologists, as primarily social scientists, do not have a background in the natural sciences. This can pose a problem because they need to obtain chemical and physical analyses on samples to perform their research. This manual is an essential source of information for those students without a background in science, but also a comprehensive overview that those with some understanding of archaeological science will find useful. The manual provides readers with the knowledge to use archaeological science methods to the best advantage. It describes and explains the analytical techniques in a manner that the average archaeologist can understand, and outlines clearly the requirements, benefits, and limitations of each possible method of analysis, so that the researcher can make informed choices. The work includes specific information about a variety of dating techniques, provenance studies, isotope analysis as well as the analysis of organic (lipid and protein) residues and ancient DNA. Case studies illustrating applications of these approaches to most types of archaeological materials are presented and the instruments used to perform the analyses are described. Available destructive and non-destructive approaches are presented to help archaeologists select the most effective technique for gaining the target information from the sample. Readers will reach for this manual whenever they need to decide how to best analyze a sample, and how the analysis is performed.
Download or read book Archaeological Chemistry written by Zvi Goffer and published by John Wiley & Sons. This book was released on 2006-08-04 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical study of archaeological materials Archaeological Chemistry, Second Edition is about the application of the chemical sciences to the study of ancient man and his material activities. The text of the book centers on the use of chemical methods, but also refers to the contributions of physics, biology, and genetics to archaeological research. Subjects discussed in the book include the determination of the nature of ancient materials, their provenance and age, the technologies used for the production of man-made materials, and the analysis of ancient human and animal remains (such as bone, dried blood, and coprolites), which yields information on ancient diets, kinship, habitancy, and migratory patterns. New developments in analytical chemistry and in related disciplines, which have contributed to archaeological research since the first edition of the book was published, are dealt with in this edition, which also includes: * Updated information on the study of the nature, age, and provenance of ancient materials * New sections on organic, biological and genetic studies * Glossary * Extensive bibliography The book is intended primarily for archaeologists, physical anthropologists and students of archaeology and physical anthropology, but will also be of use to conservators, curators, and art historians. Natural scientists reading it will become acquainted with advances in archaeological research which were made possible only by the application of chemical, physical, and biological methods and techniques.
