Taschenbuch. Zustand: Neu. Neuware - Why did the drug thalidomide affect unborn babies What is the chemical difference between sucrose and lactose in your food Stereochemistry holds the answer and is essential to understand the chemistry of life.Stereochemistry often causes confusion amongst students when they first encounter it because it requires the chemist to visualise molecules in 3D, which can be difficult. In this book we deal with tricky concepts like conformation and configuration, how to represent them accurately and how to use the correct terms to describe them in both organic and inorganic chemistry. We involved students in the writing process to ensure we deal with areas that they find difficult, using clear language. With exercises designed to focus on common errors and misconceptions, real life examples, and practical hands-on exercises coupled with visualisation tips, our intention is to give you the tools to become confident in stereochemistry. Complementing mainstream organic textbooks, or self-study, this book is for anyone who has struggled with describing alkenes as E or Z, assigning R and S absolute configurations, drawing Newman projections or chair representations of cyclohexanes, axial chirality, understanding the stereochemistry of octahedral metal complexes and explaining surprising features of NMR spectra.Chemistry Student Guides are written with current students involved at every stage, guiding the books through the most challenging aspects of the topic.

Taschenbuch. Zustand: Neu. Neuware - Presenting the fundamental topics in glass science and technology, this concise introduction includes glass formation, crystallization, and phase separation. Glass structure models, with emphasis on the oxygen balance method, are presented in detail. Several chapters discuss the viscosity, density, thermal expansion, and mechanical properties of glasses as well as their optical and magnetic behavior and the diffusion of ions, atoms, and molecules and their effect on electrical conductivity, chemical durability, and other related behavior. In addition to the effects of atomic structure on the properties of glasses, the effects of phase separation, crystallization, and water content, which are neglected in most texts, are discussed extensively. Glass technology is addressed in chapters dealing with the raw materials for producing glasses, batch calculations, and the melting and fining processes. The compositions, properties, and production of commercial glasses are also presented. A chapter is devoted to the use of thermal analysis in the study of glasses, including their crystallization behavior. This expanded, third edition, includes new chapters on doped vitreous silica and the, often overlooked, role of halides on glass formation and properties. In addition, solutions to all of the exercises at the ends of chapters are included for the first time in this edition. This introductory text is ideal for undergraduates in materials science, ceramics, or inorganic chemistry. It will also be useful to the graduate student, engineer, or scientist seeking basic knowledge of the formation, properties, and production of glass in support of their work.

Buch. Zustand: Neu. Neuware - Both genes and environment have profound effects upon our health. While some environmental factors such as polluted air are high in the public consciousness, there are many other pathways for people's exposure to toxic chemicals, such as through food, water and contaminated land. It is not only chemicals that can affect health; environmental radioactivity, pathogenic organisms and our changing climate also have implications for public health, and all contribute to the global burden of disease, leading to both disability and deaths of millions of people annually across the world. An understanding of the pathways of environmental exposure, and its effects upon health is key to developing regulations and behaviours that reduce or prevent exposure, and the consequent impacts upon health.

Buch. Zustand: Neu. Neuware - Food additives play a vital role in allowing food manufacturers to provide the range of foods that are available in the developed countries of the world. Additives cover a considerable range from the recognisable sodium bicarbonate used to make cakes in the domestic kitchen to mono- and di- acetyltartaric esters of mono- and diglycerides of fatty acids used as emulsifiers in commercial bread production. They include curcumin, the yellow colour in turmeric, beeswax and citric acid, the acid in citrus fruit, as well as substances prepared synthetically. It has long been fashionable in the media to criticise additives and, in so doing, to lump them all together but this ignores their diversity, their vital role in food production and preservation and the extensive testing they have undergone before being approved. This book outlines why additives are used, the testing regime within Europe, and a complete listing of all additives permitted within the EU.

Buch. Zustand: Neu. Neuware - The nanopore provides a highly electrochemically confined space within which single-molecule characteristics can be efficiently converted into measurable electrochemical signatures with high temporal and current resolution. Aimed at developing the concept of the electrochemical confined space in analysing single molecules, this book serves as a stepping-stone to many exciting discoveries in nanopore-based analysis of biological processes and chemical reactions in confined space.

Buch. Zustand: Neu. Neuware - Catalysis remains a key technology in a huge number of industrial processes in the 21st century. The catalytic properties of precious metals such as platinum and palladium are well understood. However, these metals are expensive and their supply is limited. Earth-abundant elements such as iron and nickel are, as the name suggests, in plentiful supply and much cheaper to use, but research on their use in catalysis has, historically, lagged behind. As researchers and companies increasingly look for ways to reduce costs and improve the sustainability of their processes there has been a renewed interest in these earth-abundant elements.

Buch. Zustand: Neu. Neuware - Turmeric belongs to the family Zingiberaceae and is a yellow spice of high economic importance due to its medicinal value. Cultivated in tropical and sub-tropical regions around the world, it is used extensively as a colouring, flavouring and preserving agent. In recent years, several drugs derived from natural products have been developed and current drug research is actively investigating the possible therapeutic roles of many Ayurvedic medicines, most notable among those being examined is turmeric. The wide range of pharmacological activities attributed to turmeric come mainly from curcuminoids and two related compounds, demethoxycurcumin and bisdemethoxycurcumin. This comprehensive book brings together the research carried out on the constituents obtained from turmeric and highlights their chemical and biological activities. Comprising 17 chapters, each written by experts in their respective field and curated by authorities, it will be invaluable to all those who are involved in the production, processing, marketing, and the use of turmeric. Appealing to researchers and professionals in natural products, nutraceuticals and food chemists, this book is exposing some of the myths and showing areas for possible future use.

Buch. Zustand: Neu. Neuware - Targeting protein degradation using small molecules is one of the most exciting therapeutic strategies in decades and a rapidly growing area of research. Since a large portion of the proteome lacks a small molecule ligand or enzymatic active site, there has been much interest in the development of novel technologies to address this so far undruggable proteome. In particular, the development of proteolysis targeting chimera (PROTACs) as potential drugs capable of recruiting target proteins to the cellular quality control machinery for elimination has opened new avenues for chemical biology and drug discovery to address traditionally 'difficult to target' proteins. Since their initial description, PROTACs have been shown to be a versatile technology capable of inducing the degradation of a great variety of proteins including transcription factors, kinases, cytosolic proteins, and nuclear epigenetic readers. The broad applicability of this approach with regard to the different types of intracellular proteins that can be degraded and the variety of E3 ligases that can be engaged suggests that future PROTAC-based drugs could be developed to treat a broad spectrum of severe diseases. Leading academic and industrial experts deliver an overview of recent trends in controlling protein levels within cells by applying small molecule tools and drugs including an outlook on current and future developments of protein degrading small molecules and beyond.

The exponential growth in renewable energy generation implies that there will be strong market pull for chemical energy storage technology in the near future, and here carbon dioxide utilization must play a central role. The electrochemical conversion of carbon dioxide is key in achieving these goals.

Buch. Zustand: Neu. Neuware - Alexander Todd, the 1957 Nobel laureate in chemistry is credited with the statement: 'where there is life, there is phosphorus'. Phosphorus chemical biology underlies most of life's reactions and processes, from the covalent bonds that hold RNA and DNA together, to the making and spending 75 kg of ATP every day, required to run almost all metabolic and mechanical events in cells. Authored by a renowned biochemist, The Chemical Biology of Phosphorus provides an in-depth, unifying chemical approach to the logic and reactivity of inorganic phosphate and its three major derivatives (anhydrides, mono- and diesters) throughout biology to examine why life depends on phosphorus. Covering the breadth of phosphorus chemistry in biology, this book is ideal for biochemistry students, postgraduates and researchers interested in the chemical logic of phosphate metabolites, energy generation, biopolymer accumulation and phosphoproteomics.
