Although contributing to the nutritional quality of the foods we consume, proteins also act as integral components by virtue of their diverse functional properties. The expression of these functional properties during the preparation, processing and storage of foods is largely dictated by changes to the structure or structure-related properties of the proteins involved. This work describes the nature of structure-function relationships so that the use of food protein sources can be optimized. The first section uses food systems as examples to demonstrate the intricate nature of the structure-function relationship. Later chapters discuss the techniques which are used to examine structural parameters or establish relationships between protein structure and function. This guide should prove useful for food chemists, scientists and technologists, and can serve as a reference for students of this field.

This comprehensive contributed volume presents an account of current research and applications of chemical processes occurring at the interfaces of water with naturally occurring solids. Interactions of solutes with the solid surfaces are looked at from a mechanistic and dynamic point of view rather than a descriptive one. Processes discussed and concepts presented are applicable to all natural waters (oceans and fresh waters as well as soil and sediment water systems) and to the surfaces of natural solids such as minerals, soils, sediments, biota, and humus. Chapters progress from theoretical models and laboratory studies to applications in natural water, soil, and geochemical systems, emphasizing those processes that regulate the distribution and concentration of elements and compounds. Topics covered include adsorption mechanisms in aquatic surface chemistry, the electric double layer at the solid-solution interface, aspects of molecular structure in surface complexes: spectroscopic investigations, interpretation of metal complexation by heterogeneous complexants, the role of colloids in the partitioning of solutes in natural waters, and from molecules to planetary environments and understanding global change.

In the current edition, Selenium: Its Molecular Biology and Role in Human Health expands extensively on the previous editions providing readers with the most significant advances in the rapidly developing selenium field. Evidence from epidemiology and veterinary science supports the essential role of selenium in (human) health, but its split personality in both preventing and supporting cancer and also in promoting insulin resistance has become more clearly defined. The pivotal role of glutathione peroxidase 4 in a new process of programmed cell death, ferroptosis, brings new impetus to the field. Recently defined mutations in selenoprotein and biosynthesis factor genes have been identified in patients, and the resulting disorders further emphasize the significance of selenoproteins in human health. The mechanism of selenoprotein biosynthesis, the functions of selenoproteins, and the roles of dietary selenium have been further elucidated, and new regulatory mechanisms involving selenoproteins discovered. The book, therefore, covers the breadth of current selenium research. With up-to-date chapters written by leaders in their fields, it serves as an invaluable resource for novices as well as specialists.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

An authoritative review of the state of the art in the Nuclear Overhauser Effect—essential information for organic chemists, biochemists, biophysicists, and NMR spectroscopists

The field of NMR spectroscopy has seen tremendous growth in the last twenty years, particularly advances relating to Nuclear Overhauser Effect (NOE) spectroscopy—the most powerful technique for obtaining structural information on molecules in solution. Extensive and engaging, the Second Edition of the leading reference on the NOE is significantly updated to reflect the latest changes and new approaches in the field.

Neuhaus and Williamson provide an essential guide to the complexities and use of the NOE in a readily accessible, straightforward manner. Their practical handbook features a new chapter addressing the use of NOE data to calculate biomolecular structures. Chapters dealing with the kinetics of the NOE, the effects of exchange and internal motion, and applications of the NOE, are also extensively revised. Cross-referenced in remarkable depth, The Nuclear Overhauser Effect is organized into three main parts:

• Part I describes the theory of the Nuclear Overhauser Effect in a clear, comprehensive fashion
• Part II discusses the considerations involved in implementing NOE experiments, including full coverage of all necessary details for both new and established techniques
• Part III offers examples of how the NOE is used, including applications to defining molecular geometry, stereochemistry, conformation, and biomolecular structure and interactions

Originally published by Bentham and now distributed by Elsevier, Recent Advances in Medicinal Chemistry, Volume 1 covers leading-edge research and recent developments in rational drug design, synthetic chemistry, bioorganic chemistry, high-throughput screening, combinatorial chemistry, drug targets, and natural product research and structure-activity relationship studies. The fourteen updated reviews include unique experimental data and references, and each article highlights an important topic in current medicinal chemistry research. Topics covered include: aureolic acid group of anti-cancer antibiotics and non-steroidal anti-inflammatory drugs; aromatase inhibitors in adjuvant endocrine treatment of early-stage breast cancer in postmenopausal women; Rho GTPases and statins in targeting and developing therapies for tumors; and more.

The contributors to this text, who are all biochemists who worked during the 1950s and 60s, describe what appears to them to be the conceptually significant developments in biochemistry since the mid 1950s and how these were achieved. Their aim is to make their subjects intelligible to other scientists not expert in their field.

This book describes how epigenetic context, in a large sense, affects gene expression and the development of an organism, using the asymptotic limit theorems of information theory to construct statistical models useful in data analysis. The approach allows deep understanding of how embedding context affects development. We find that epigenetic information sources act as tunable catalysts, directing ontogeny into characteristic pathways, a perspective having important implications for epigenetic epidemiology. In sum, environmental stressors can induce a broad spectrum of developmental dysfunctions, and the book explores a number of pandemic chronic diseases, using U.S. data at different scales and levels of organization. In particular, we find the legacy of slavery has been grossly compounded by accelerating industrial decline and urban decay. Individual chapters are dedicated to obesity and its sequelae, coronary heart disease, cancer, mental disorders, autoimmune dysfunction, Alzheimer's disease, and other conditions. Developmental disorders are driven by environmental factors channeled by historical trajectory and are unlikely to respond to medical interventions at the population level in the face of persistent individual and community stress. Drugs powerful enough to affect deleterious epigenetic programming will likely have side effects leading to shortened lifespan. Addressing chronic conditions and developmental disorders requires significant large-scale changes in public policy and resource allocation.

This new edition provides a comprehensive look at the molecular genetics and biochemical basis of fungal biology, covering important model organisms such as Aspergilli while also integrating advances made with zygomycetes and basidiomycetes. This book groups a total of 15 chapters authored by expert scholars in their respective fields into four sections. Five chapters cover various aspects of gene expression regulation. These range from regulation in organismal interactions between parasitic fungi and their host plant, heavy metal stress and global control of natural product genes to conidiation and regulation through RNA interference. Two chapters are dedicated to signal transduction, highlighting MAP-kinase-dependent signaling and heterotrimeric G-proteins. Fungal carbohydrates are the subject of the third section, which addresses both polymeric cell wall carbohydrates and trehalose as an important, low molecular weight carbohydrate. The fourth section emphasizes the metabolism of major elements (carbon, nitrogen, sulfur) and critical cellular pathways for primary and secondary products.

This fourth volume in the series covers such topics as endogenous fuels, electric organs, histidine-related dipeptides, and origins of luciferins. The book will be invaluable to fisheries scientists, aquaculturists, and animal biochemists, physiologists and endocrinologists; it will provide researchers and students with a pertinent information source from theoretical and experimental angles.

This thesis reports the latest developments in the direct amination of various C H bonds using an H Zn exchange/electrophilic amination strategy. McDonald and co-workers reveal this approach to be a rapid and powerful method for accessing a variety of functionalized amines. The material outlined in this book shows how McDonald achieved C H zincation using strong, non-nucleophilic zinc bases and subsequent electrophilic amination of the corresponding zinc carbanions with copper as a catalyst and O-benzoylhydroxylamines as the electrophilic nitrogen source. McDonald's findings are of relevance to medicinal chemistry, drug discovery and materials science. Her thesis is a source of inspiration for scientists entering the field and students beginning their PhD in a related area.

The cyclic purine nucleotides 3',5'-cAMP and 3',5'-cGMP are well-established second messengers. cGMP has recently been covered in a volume of the Handbook of Experimental Pharmacology (volume 191). In addition to 3',5'-cAMP and 3',5'-cGMP, so-called non-canonical cyclic nucleotides exist. These comprise the cyclic pyrimidine nucleotides 3',5'-cCMP and 3',5'-cUMP, the purine nucleotide 3',5'-cIMP, the 2',3'-nucleoside monophosphates and cyclic dinucleotides. In this volume of the Handbook of Pharmacology, word-leading experts in the field summarize our current knowledge on these non-canonical cyclic nucleotides, discuss open questions, future research directions and the pharmacotherapeutic implications. Special emphasis will be given to the emerging roles of 3',5'-cCMP and 3',5'-cUMP as second messengers with regard to generators, effectors, biological functions, inactivation and bacterial toxins. The role of 3',5'-cIMP as potential second messenger will also be critically discussed. Furthermore, we will consider transport of cyclic nucleotides and their potential role as first messengers. The role of the cyclic dinucleotide cGAMP in the immune system will covered, too. Lastly, the book will present important methodological aspects ranging from mass-spectrometric methods for cyclic nucleotide detection to the synthesis of nucleotide analogs as experimental tools and holistic methods for analysis of cyclic nucleotide effects.
