  amino acid composition analysis: Analytical Microbiology Methods A. Fox, L. Larsson, S.L. Morgan, G. Odham, 2013-11-11 The First International Symposium on the Interface between Analytical Chemistry and Microbiology: Applications of Chromatography and Mass Spectrometry was held June 1987 at the University of South Carolina, Columbia, SC, U.S.A. The purpose of the Interface meeting was to forge connections between analytical chemists and microbiologists that are using chromatography and mass spectrometry to solve common problems. The goals were admirably fulfilled. Nearly a hundred participants from seven European countries, Japan, and the United States participated in hearing twenty-three plenary talks and thirty-six submitted papers and posters. The papers and discussions displayed the breadth and depth of current research applications and revealed future directions. This book Analytical Microbiology Methods: Chromatography and Mass Spectrometry is loosely based on some of the presentations and discussions at the meeting. Each chapter describes specific methodology and applications in the context of the relevant scientific background. The present book continues the theme of an earlier book, Gas Chromatography/Mass Spectrometry Applications in Microbiology, edited by G. Odham, L. Larsson, and P-A. Mardh, published by Plenum Press in 1984.

  amino acid composition analysis: Protein Sequence Determination Saul B. Needleman, 2013-06-29 All the King's horses and all the King's mm couldn't put Humpty Dumpty together again. It is entirely possible that the difficulty facing all the King's men was principally the lack of a sufficient guide to the techniques of reassembling from a series of small components, the original entity. It is the sincere hope of the editor of the present work and of each of the contributing authors that the modern researcher will not face a similar predicament in his endeavours to reconstruct the complete primary sequence of a protein from the array of component amino acids. Rather, it is the intent that, with this volume, he may proceed untimorously if not with outright confidence toward achieving his purpose. To the newcomer in protein sequencing, compelled by necessity, or fascination, to investigate the exact order of amino acids in proteins, the question of where to begin - or how to do it is urgent. To those more skilled, a ready source of additional techniques should nevertheless be of value. This volume attempts to present in a single source a discussion of the methods and techniques useful to the determination of the primary structures of proteins and peptides. Hopefully, this book will tell the reader how to do it.
  amino acid composition analysis: Prediction of Protein Structure and the Principles of Protein Conformation G.D. Fasman, 2012-12-06 The prediction of the conformation of proteins has developed from an intellectual exercise into a serious practical endeavor that has great promise to yield new stable enzymes, products of pharmacological significance, and catalysts of great potential. With the application of predic tion gaining momentum in various fields, such as enzymology and immunology, it was deemed time that a volume be published to make available a thorough evaluation of present methods, for researchers in this field to expound fully the virtues of various algorithms, to open the field to a wider audience, and to offer the scientific public an opportunity to examine carefully its successes and failures. In this manner the practitioners of the art could better evaluate the tools and the output so that their expectations and applications could be more realistic. The editor has assembled chapters by many of the main contributors to this area and simultaneously placed their programs at three national resources so that they are readily available to those who wish to apply them to their personal interests. These algorithms, written by their originators, when utilized on pes or larger computers, can instantaneously take a primary amino acid sequence and produce a two-or three-dimensional artistic image that gives satisfaction to one's esthetic sensibilities and food for thought concerning the structure and function of proteins. It is in this spirit that this volume was envisaged.
  amino acid composition analysis: Amino Acid Composition and Biological Value of Cereal Proteins Radomir Lásztity, Máté Hidvegi, 1985-07-31 Cereals belong to the most important elements in the history of mankind. From the beginning of agriculture, cereals have been by far the most important staple food in the world. Although the cereal consumption decreased to a low level in the developed countries in Europe and North America, in the devel oping countries over two-thirds of the calorie and protein intake is based on cereals. A substantial quantity of cereals goes indirectly into food via feed to animals. Generally, cereal proteins are classified as proteins of lower biological value because of shortage in lysine and some other essential amino acids. Recent developments in the de termination and evaluation of the biological value of proteins and protein mixtures suggest that the oversimplified earlier evaluation of cereal proteins must be reviewed. This book contains the edited proceedings of the Inter national Symposium on Amino Acid Composition and Biological Value of Cereal Proteins, held in Budapest, Hungary, Hay 31- June 1, 1983, under the sponsorship of the International Association for Cereal Chemistry, Hungarian Scientific Society for Food Industry and Grain Trust, Hungary, with supplemental invited contributions. Scientists (biologist, plant breeders, farmers, chemists, biochemists, engineers, food technologists and nutritionists) from 17 countries presented and reviewed, along with partici pants from 20 countries, the recent methodology and trends in the determination of the biological value of cereal proteins, v the amino acid composition of cereal proteins and factors in fluencing the composition and the role of cereal proteins in nutrition and animal feeding.
  amino acid composition analysis: Salts of Amino Acids Michel Fleck, Aram M. Petrosyan, 2014-07-08 Over the last decades, amino acids have been found to be of importance in many fields of science. Apart from their biological function, this family of organic compounds has been employed in the synthesis of a vast variety of salts, with impact on areas such as materials science, pharmaceutical or physical research. This covers a wide range, from the discovery of important ferroelectrics or non-linear optical materials to nutrients, flavor enhancers or drugs. This book describes amino acids and their salts with cations, anions and inorganic compounds from a chemical, physical and crystallographical point of view. Additional data on structural properties, crystal growth and the relation of structure and physical properties of amino acid salts is discussed.
  amino acid composition analysis: Chemistry and Biochemistry of the Amino Acids Graham Barrett, 2012-12-06 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.

  amino acid composition analysis: The Role of Protein and Amino Acids in Sustaining and Enhancing Performance Institute of Medicine, Committee on Military Nutrition Research, 1999-09-15 It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.
  amino acid composition analysis: Immobilized PH Gradients: Theory and Methodology P. G. Righetti, 1990 Immobilized pH gradients (IPG) represent the most advanced development of isoelectric focusing (IEF). Originally developed to overcome all the problems of IEF in soluble amphoteric buffers (CA) (such as pH gradient instability, complexation with CA chemicals, unreproducibility of pH gradients, protein precipitation at the pI), it turned out to be an entirely new technique, quite different in principle and operation from conventional IEF. The book is thus meant to bring the reader up to date with this fast developing field. The book is divided into six chapters containing information on: detailed treatment of all the chemistry of the Immobiline chemicals; theory of pH gradient generation (computer simulations, tables with all the possible pH recipes); all analytical aspects of IPGs, including staining techniques, blotting etc.; two-dimensional maps, with a detailed treatise of advantages and limitations; preparative aspects of IPGs, including comparison with other preparative electrophoretic techniques; some examples of applications, including genetic and forensic analysis, blood polymorphism etc.The book is extensive and up-to-date, while also extensively covering the theory. Clearly written, with easily accessible information, the volume is a worthy asset to the Lab. Techniques series.
  amino acid composition analysis: Principles and Applications of Gas Chromatography in Food Analysis Michael H. Gordon, 2013-03-08 The food analyst plays an important role in modern society. Stricter control over additives in food and concern about the effects of contamination of food by industrial and agricultural chemicals are among the developments which are leading to an increasing emphasis on detailed and accurate analysis of food. However. analysis of food is required for many reasons, including detection of toxic components, monitoring legislation, detecting adulteration, formulation of controlled diets, controlling formulation during product development and detecting changes in food during storage and processing. Foods comprise a complex mixture of components and food analysis requires efficient methods of separation with high sensitivity or specificity of detection. Although many food components are involatile or thermally labile and therefore not suitable for analysis by gas chromatography, other components are volatile and this technique is the preferred analytical method. Developments in methods of derivati zation, injector design and column technology have also extended the applicability of gas chromatography to the analysis of relatively involatile compounds.
  amino acid composition analysis: Sequence — Evolution — Function Eugene V. Koonin, Michael Galperin, 2013-06-29 Sequence - Evolution - Function is an introduction to the computational approaches that play a critical role in the emerging new branch of biology known as functional genomics. The book provides the reader with an understanding of the principles and approaches of functional genomics and of the potential and limitations of computational and experimental approaches to genome analysis. Sequence - Evolution - Function should help bridge the digital divide between biologists and computer scientists, allowing biologists to better grasp the peculiarities of the emerging field of Genome Biology and to learn how to benefit from the enormous amount of sequence data available in the public databases. The book is non-technical with respect to the computer methods for genome analysis and discusses these methods from the user's viewpoint, without addressing mathematical and algorithmic details. Prior practical familiarity with the basic methods for sequence analysis is a major advantage, but a reader without such experience will be able to use the book as an introduction to these methods. This book is perfect for introductory level courses in computational methods for comparative and functional genomics.
  amino acid composition analysis: Amino Acid Analysis Michail A. Alterman, Peter Hunziker, 2011-12-02 Amino Acid Analysis (AAA) is an integral part of analytical biochemistry. In a relatively short time, the variety of AAA methods has evolved dramatically with more methods shifting to the use of mass spectrometry (MS) as a detection method.

Enzymology and modern concepts of enzyme kinetics are then introduced, taking into account the physiological, pharmacological and medical significance of this often neglected topic. This is followed by thorough coverage of hæmoglobin and myoglobin, immunoproteins, motor proteins and movement, cell-cell interactions, molecular chaperones and chaperonins, transport of proteins to various cell compartments and solute transport across biological membranes. Proteins in the laboratory are also covered, including a detailed description of the purification and determination of proteins, as well as their characterisation for size and shape, structure and molecular interactions. The book emphasises the link between protein structure, physiological function and medical significance. This book can be used for graduate and advanced undergraduate classes covering protein structure and function and as an introductory text for researchers in protein biochemistry, molecular and cell biology, chemistry, biophysics, biomedicine and related courses. About the author: Dr. Buxbaum is a biochemist with interest in enzymology and protein science. He has been working on the biochemistry of membrane transport proteins for nearly thirty years and has taught courses in biochemistry and biomedicine at several universities.
  amino acid composition analysis: Practical Protein Bioinformatics Florencio Pazos, Mónica Chagoyen, 2014-11-28 This book describes more than 60 web-accessible computational tools for protein analysis and is totally practical, with detailed explanations on how to use these tools and interpret their results and minimal mentions to their theoretical basis (only when that is required for making a better use of them). It covers a wide range of tools for dealing with different aspects of proteins, from their sequences, to their three-dimensional structures, and the biological networks they are immersed in. The selection of tools is based on the experience of the authors that lead a protein bioinformatics facility in a large research centre, with the additional constraint that the tools should be accessible through standard web browsers without requiring the local installation of specific software, command-line tools, etc. The web tools covered include those aimed to retrieve protein information, look for similar proteins, generate pair-wise and multiple sequence alignments of protein sequences, work with protein domains and motifs, study the phylogeny of a family of proteins, retrieve, manipulate and visualize protein three-dimensional structures, predict protein structural features as well as whole three-dimensional structures, extract biological information from protein structures, summarize large protein sets, study protein interaction and metabolic networks, etc. The book is associated to a dynamic web site that will reflect changes in the web addresses of the tools, updates of these, etc. It also contains QR codes that can be scanned with any device to direct its browser to the tool web site. This monograph will be most valuable for researchers in experimental labs without specific knowledge on bioinformatics or computing.
  amino acid composition analysis: Bitterness Michel Aliani, Michael N. A. Eskin, 2017-04-17 The increasing demand for healthy foods has resulted in the food industry developing functional foods with health-promoting and/or disease preventing properties. However, many of these products bring new challenges. While drugs are taken for their efficacy, functional foods need to have tastes that are acceptable to consumers. Bitterness associated with the functional foods is one of the major challenges encountered by food industry today and will remain so in years to come. This important book offers a thorough understanding of bitterness, the food ingredients that cause it and its accurate measurement. The authors provide a thorough review of bitterness that includes an understanding of the genetics of bitterness perception and the molecular basis for individual differences in bitterness perception. This is followed by a detailed review of the chemical structure of bitter compounds in foods where bitterness may be considered to be a positive or negative attribute. To better understand bitterness in foods, separation and analytical techniques used to identify and characterize bitter compounds are also covered. Food processing can itself generate compounds that are bitter, such as the Maillard reaction and lipid oxidation related products. Since bitterness is considered a negative attribute in many foods, the methods being used to remove and/mask it are also thoroughly discussed.

  amino acid composition analysis: Comparative Virology Karl Maramorosch, Edouard Kurstak, 2014-06-28 Comparative Virology provides an integrated comparison of viruses, based on their chemical and morphological characteristics. These descriptions will not only give the reader a background but also a detailed analysis of the various groups. In some instances the groups are still host related, as in the case of bacteriophages and polyhedral insect viruses. In others, for instance in pox viruses, the group comprises viruses of vertebrates and invertebrates. The hosts of the bacilliform Rhabdovirales range from man and other warm-blooded vertebrates through invertebrate animals to plants. A special chapter is devoted to viruses devoid of protein—a group that is of great interest and that has only recently been recognized. Since there is historical and practical interest in écologie groupings, such as arboviruses and oncogenic viruses, chapters on such groups have also been included. The book opens with a discussion on the classification of viruses. Chapters dealing with DNA viruses and RNA viruses follow, and the ecologically and disease-oriented groups complete the volume. It is hoped that Comparative Virology will help bring unity to the science of virology through the comparative approach that is not dependent on virus-host interactions. The combined efforts of eminent contributors to discuss and evaluate new information will hopefully benefit all who are interested in virology

  amino acid composition analysis: Protein Sequencing Protocols Bryan John Smith, 2008-02-02 Determination of the protein sequence is as important today as it was a half century ago, even though the techniques and purposes have changed over time. Mass spectrometry has continued its recent rapid development to find notable application in the characterization of small amounts of protein, for example, in the field of proteomics. The “traditional” chemical N-terminal sequencing is still of great value in quality assurance of the increasing number of biopharmaceuticals that are to be found in the clinic, checking processing events of recombinant proteins, and so on. It is joined in the armory of me- ods of protein analysis by such techniques as C-terminal sequencing and amino acid analysis. These methods are continually developing. The first edition of Protein Sequencing Protocols was a “snapshot” of methods in use in protein biochemistry laboratories at the time, and this, the second edition, is likewise. Methods have evolved in the intervening period, and the content of this book has similarly changed, the content of some chapters having been superceded and replaced by other approaches. Thus, in this edition, there is inclusion of approaches to validation of methods for quality assurance work, reflecting the current importance of biopharmaceuticals, and also a guide to further analysis of protein sequence information, acknowledging the importance of bioinformatics.

  amino acid composition analysis: NMR Spectroscopy in Pharmaceutical Analysis Iwona Wawer, Bernd Diehl, 2017-07-07 For almost a decade, quantitative NMR spectroscopy (qNMR) has been established as valuable tool in drug analysis. In all disciplines, i. e. drug identification, impurity profiling and assay, qNMR can be utilized. Separation techniques such as high performance liquid chromatography, gas chromatography, super fluid chromatography and capillary electrophoresis techniques, govern the purity evaluation of drugs. However, these techniques are not always able to solve the analytical problems often resulting in insufficient methods. Nevertheless such methods find their way into international pharmacopoeias. Thus, the aim of the book is to describe the possibilities of qNMR in pharmaceutical analysis. Beside the introduction to the physical fundamentals and techniques the principles of the application in drug analysis are described: quality evaluation of drugs, polymer characterization, natural products and corresponding reference compounds, metabolism, and solid phase NMR spectroscopy for the characterization drug substances, e.g. the water content, polymorphism, and drug formulations, e.g. tablets, powders. This part is accompanied by more special chapters dealing with representative examples. They give more detailed information by means of concrete examples. Combines theory, techniques, and concrete applications—all of which closely resemble the laboratory experience Considers international pharmacopoeias, addressing the concern for licensing Features the work of academics and researchers, appealing to a broad readership

  amino acid composition analysis: Eukaryotic MRNA Processing Adrian Krainer, 1997 This volume focuses on the major aspects of post-transcriptional mRNA processing in the nucleus of eukaryotic cells. Each of the described mRNA reactions is required for proper gene expression and can also serve as a control point for regulating the expression of many genes, for example duringembryonic development or in different cell types. The different chapters review the assembly of newly synthesized nuclear mRNA transcripts into hnRNP particles and catalytically active spliceosomes; the structure and mechanism of action of small nuclear ribonucleoprotein particles and proteinfactors that catalyse pre-mRNA splicing in mammalian cells and in yeast; the regulation of gene expression and generation of protein isoform diversity by alternative splicing; the mechanisms of 3' end cleavage and polyadenylation; the architecture of the cell nucleus in relation to these processesand to the localization of the relevant substrates and factors; the diverse mechanisms of RNA processing by ribozymes and their potential relevance for nuclear mRNA processing; the mechanism of spliced-leader addition by trans-splicing in nematodes and trypanosomes; and the process ofinsertion/deletion mRNA editing in kinetoplasmid protozoa. In each chapter, leading researchers have provided detailed, critical reviews of the history, experimental approaches, major advances, current ideas and models, as well as future directions, for each of these active areas of research.
  amino acid composition analysis: Amino Acid Analysis Protocols Catherine Cooper, 2000-09-05 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.
