This fully updated and expanded second edition of a highly popular text book focuses on the structure and mechanism in carbohydrate chemistry and biochemistry. Carbohydrates play important roles in biological systems as energy sources, as structural materials, and as informational structures (when they are often attached to proteins or lipids). Their chemical reactivity and conformational behaviour is governed by mechanistic and stereochemical rules, which apply as much to enzymic as to non-enzymic reactivity. The same principles of reactivity and conformation govern changes brought about in the process industries, such as pulp, paper and food. Extensively referenced with citations and a detailed index, the book contains everything the reader needs to know to start a carbohydrate research project with one of the real strengths being the treatment and integration of the important physical-chemical principles and methods (though lead references only are given to the finer points of carbohydrate synthesis). The book is suitable for both researchers who are new to the subject and those more established as well as a readership from diverse backgrounds and interests, including chemists, biochemists, food scientists and technologists involved with the processing of polysaccharides in the paper, textile, cosmetics, biofuels and other industries.

Proteins are an important nutrient and ingredient in food as well as in nutritional supplements. The application and take up of food proteins, especially plant proteins, has been limited due to their undesirable sensory properties, e.g. taste, odour, and chalky mouth feel. This will need to change if the availability of meat protein becomes scarcer. Documenting the latest research, this book is the first overview of the recent advances in flavour research of food proteins, with an emphasis on the major plant proteins, e.g. soy and pulse proteins. The topics to be covered include sensory and instrumental characterization of flavour compounds in food proteins, how flavour profiles in food proteins can be formed or altered, research advances of individual food proteins, the use of food protein products as flavouring ingredients, and future trends of flavouring food proteins. There is a growing interest in using plant proteins in food formulation and industrial applications, but no book has yet covered this systematically until now. Summarizing research advances in consumer studies and flavour chemistry that focus on food proteins, the book will discuss the flavour properties and problems in each major and novel food protein source for the academic and industry market.

In the human body, there are millions of living microorganisms involved in protecting the body from invaders, helping digestion and regulating moods, but there are also harmful pathogens that cause infectious diseases. For instance, the coronavirus (COVID-19) has caused considerable loss of life since its outbreak. Comprehensive analysis and characterization of microbes is of significant importance to understand the function and role of microorganisms, and rapid detection and identification of unknown pathogens are essential in early diagnosis, treatment monitoring and personalized medicine. Mass spectrometry is a technique to ionize molecules and detect the mass-to-charge ratio of the generated ions. The technique is widely used in hospitals for pathogenic bacteria identification, as well as in environmental science and food science for biosafety control. This book summarizes the most recent development of mass spectrometry techniques in microbial analysis, including mass spectrometry-based microbial identification, bacterial antimicrobial resistance study, data mining algorithm development, omics for microbial research, applications in clinical diagnosis, environmental science and food science, and more. It will guide researchers in the field, and those who are about to enter the field, in the most appropriate methods to characterize microbes and enable their detection.

Antibiotic resistance is a global health concern. Strains of pathogenic microorganisms that have developed resistance to multiple antibiotics, such as MRSA, are extremely difficult to treat, and alternative methods for tackling pathogenic microorganisms are in demand. One potential target for new therapeutics is inhibition of quorum sensing: how microorganisms communicate and form biofilms in a density-dependent manner. Inhibiting this system via ‘quorum quenching'(QQ) is a promising route to new pharmaceuticals and for controlling biofilm formation and growth. Quorum sensing also provides interesting possibilities in synthetic biology for producing novel products, biosensors, bioactive molecules, and so on. This book covers the biology of quorum sensing and quenching, and potential sources of QQ enzymes and other inhibitors, as well as an overview of their mechanism and potential biotech applications. The book also covers the potential for new drug development from QQ, covering a range of related topics including protein engineering, imaging and computational studies, and integrated systems. This book is an ideal companion to researchers in chemical biology and medicinal chemistry, particularly those interested in biofilm formation, quorum sensing, novel antimicrobial development, synthetic biology and enzymology.

The phytochemical constituents of plants fall into two main categories based on their role in basic metabolic processes: primary and secondary. Primary metabolites are involved in basic life functions and are similar in all living cells, whereas secondary metabolites are derived from subsidiary pathways. Although traditionally referred to as secondary metabolites, more recently these compounds have been termed ‘plant specialized metabolites', as the exact biochemical boundary between primary and secondary metabolites has not been fully established. Plant specialized metabolites are the main elements in the study and use of ‘medicinal'plants and herbs, as well as in nutrition and food chemistry. In modern medicine, plant specialized metabolites provide many of the lead compounds in the production of medicines targeted at treating a broad variety of diseases. Such metabolites also play an important role in sessile plants to resist and withstand different biotic and abiotic stresses. Plant specialized metabolites are classified according to their chemical structures and this book will present the different classes in turn, while discussing their sources and distribution in plant families, their biosynthetic pathways, and their important and notable uses in phytochemistry and pharmacology.

The physical properties associated with the saturated and trans fats obtained through partial hydrogenation of vegetable oils (PHVOs) provide the solid fat content, melting and textural properties that consumers require in food products like butter, margarines, vegetable creams, spreads, and confectionary fats. However, saturated and trans fats increase low density lipoprotein, while trans fats also lower high-density lipoprotein serum levels. These indicators increase the risk of developing cardiovascular disease, type II diabetes, stroke, and have recently been associated with metabolic syndrome. Consequently, regulatory agencies worldwide have passed legislation restricting the addition of PHVOs and their derivatives (i.e., shortenings) to food products. This has lead research groups worldwide to investigate different mechanisms to provide structural and physical properties to edible, healthy unsaturated oils. The overall objective is to achieve similar functional properties to those provided by PHVOs and shortenings to food products. This book encompasses the work of leading researchers discussing, from a scientific and technological perspective, the latest and most innovative approaches to structure edible oils without the use of trans fats. Additionally, the authors discuss practical uses and technical limitations associated with the use of'structured edible oils'in different food systems.

To thrive, every living cell must continuously gauge and respond to changes in its environment. These changes are ultimately implemented by modulating gene expression, a process that relies on transcription by Nature's most multivalent molecular machine, the RNA polymerase. This book covers progress made over the past decade understanding how this machine functions to compute the cellular state, from the atomistic structural level responsible for chemistry to the integrative level at which RNA polymerase interacts with the other key molecular machineries of the cell.

The efficient analysis of polar and charged metabolites in biological samples remains a huge challenge in the field of metabolomics. Over the past years, novel mass spectrometry-based analytical tools have been developed to enable the sensitive and efficient profiling of polar ionogenic metabolites in various biological samples. This book gives the reader a comprehensive overview of these recent technological developments. Topics covered include the use of chemical labelling strategies for allowing the analysis of polar metabolites using reversed-phase liquid chromatography–mass spectrometry (RPLC-MS) and the latest methodological developments in RPLC-MS, hydrophilic interaction liquid chromatography (HILIC)-MS and ion-pair LC-MS approaches. Attention is also paid to developments in nano-LC-MS and capillary electrophoresis–mass spectrometry methods specifically for profiling polar metabolites in small volume biological samples. The utility of ion-mobility MS and NMR spectroscopy will also be outlined. Sample preparation is the key part in the analytical workflow employed for metabolomics. Therefore, ample emphasis will be given on recent solid-phase extraction and solid-phase micro-extraction methods. Finally, analytical techniques for chiral metabolic profiling will also be considered. Discussing the state-of-the-art of the proposed topics in one single book for probing the polar metabolome, using relevant examples, is unique and needed in the metabolomics field. This book has relevance and appeal to an international audience of analytical and biomedical researchers in industry and academia.

This is the first book for some years that provides a comprehensive overview of food oral processing. It includes fundamental chapters at the beginning of each section to aid the understanding of the later more specific oral processing chapters. The field is rapidly developing, and the systems researched in the context of food oral processing become increasingly complex and therefore the fundamental sections include information on how to build complex food systems. The main coverage includes the biomechanics of swallowing, the biophysics of mouthfeel and texture as well as the biochemistry of flavours and how food microstructures can be manipulated. It contains up-to-date research findings, looking at consumer preferences and the response to these preferences by food process technologists and those developing new foods. The book will be of interest to postgraduate students and researchers in academia and industry who may be from very diverse backgrounds ranging from food process engineers to functional food developers and professionals concerned with swallowing and taste disorders.

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.

This volume aims to provide an in-depth view of the complete biochemistry of sulfur with an emphasis on aspects not covered elsewhere.

Current literature on the biochemistry of sulfur is vast and widely dispersed, as such this volume is intended as a single-source for everything concerning sulfur biochemistry from metabolic roles of inorganic sulfur, to thiol and thioether chemical biology, to the university of cysteine chemistry in proteomes. Authored by a renowned biochemist and experienced writer and educator, this book is ideal for students and researchers in biochemistry, biology and the life sciences with an interest in sulfur and its role in life.

Why does chocolate taste so good? Why do we seek'the one'? How do traits such as intelligence, creativity and violence arise and what purpose do they serve? This book links these characteristics to the origins of life, showing that the conditions necessary to bring life into existence echo through our modern day behaviour.The chemistry of the body is not only fascinating but also highly relevant to everyone, since we are all concerned with maximising our health and enjoyment of life. Currently, there are not many popular science books concerned with biochemistry. One reason for this might be the particularly complex nature of the science involved. This book starts with the fundamentals and then works towards a deeper understanding of the chemistry of human nature. Essential reading for anyone with an interest in this science and written at a level accessible to experts and non-experts alike.

Targeting protein degradation using small molecules is one of the most exciting small-molecule therapeutic strategies in decades and a rapidly growing area of research.
