Book Description
This book aims to open new fields of interest in phosphate chemistry and to suggest a new system of classification for phosphates. Due to the very rapid development of this branch of chemistry during the last thirty years and the very confusing nomenclature often used in chemical literature, this first attempt seems not only justified but necessary. The suggested classification is not revolutionary, with respect to condensed phosphates for instance, but establishes clear boundaries between some categories of compounds such as adducts and heteropolyanion-compounds. The first chapters cover the present state of phosphate chemistry in a general way and could serve as an introduction to phosphates for some categories of students or teachers. The next few chapters are devoted to more specialized topics which would be of interest to chemists, crystallographers or solid-state specialists.Some specific aspects of the crystal chemistry of phosphates, such as the geometry of the networks built by acidic phosphoric anions, for instance, are covered for the first time. The final chapter suggests some improvements for the present system of classification for phosphates.In addition, presented for the first time are the results recently obtained for the replacement of asbestos by harmless biodegradable phosphate fibers.

Book Description
Here is a fascinating reader-friendly exploration of “the phosphorus enigma.” The volume attempts to answer the questions: How did phosphorus atoms, which are produced inside the inner cores of a handful of huge stars, become concentrated in relatively high proportions in the organisms composing Earth’s biosphere? And how did these phosphate derivatives manage to be included in such a great variety of organic molecules playing essential biochemical roles in all known life forms? Due to the interdisciplinary nature of the topic, the volume is arranged in three sections. The first section introduces the fundamental concepts and notions of physics, chemistry, and biology necessary for the proper understanding of the topics discussed within an astronomical framework. The author then focuses on the role of phosphorus and its compounds within the context of chemical evolution in galaxies, considering its relevance in most essential biochemical functions as well as its peculiar chemistry under different physicochemical conditions. The third section provides an overall perspective on the role of phosphorus and its compounds in current areas of research of solid state physics, materials engineering, nanotechnology or medicine.

Book Description
Undoubtedly the chemistry of phosphorus appears more and more attractive in the sense that phosphorus presents an extraordinary versatile behaviour that allows the synthesis of a large number of different phosphorus reagents usable for applications in different fields, from biology to material science without f- getting key applications in catalysis. The full maturity of this topic of research can be explained by all the acquired knowledge over these twenty last years. Organic and inorganic chemistries of P , P and P species have been the s- in ]V v ject of thousands of publications while the chemistry of low coordinated ph- phorus derivatives experienced its hour of glory from the 1970s to the early 1990s. In parallel, interactions between phosphorus compounds and transition metals afforded many complexes, a lot of which present fascinating properties as catalysts. The interest in all these themes really is not decreasing, indeed some fas- nating areas of research are emerging or are the subject of many investigations: the medicinal chemistry of bisphosphonates, the role of phosphorus in biology, phosphorus ligands in radiopharmaceutical chemistry, phosphorus in material science, new polymers and dendrimers incorporating phosphorus, and as- metric catalysis to name but a few. Indeed researchers, benefitting from their background in basic phosphorus chemistry are developing many new fields of research.

Book Description
Due to a great chemical similarity with the biological calcified tissues, many calcium orthophosphates possess remarkable biocompatibility and bioactivity. Materials scientists use this property extensively to construct artificial bone grafts that are either entirely made of or only surface-coated with the biologically relevant calcium orthophospha

Book Description
Inorganic polyphosphates - polymers of orthophosphate linked by high-energy phosphoanhydride bonds - have been found in apparently all forms of life, from bacteria, yeasts and fungi to higher plants and animals. These polymers, which had been neglected for a long time, have become a fascinating area of research in the last few years. This volume summarizes the present state of knowledge about the metabolism and function of inorganic polyphosphates. In addition, the methods to study these polymers as well as the biotechnological applications of inorganic polyphosphates are described. The 15 chapters of this volume, dealing with different aspects of polyphosphate research, are written by experts in the field. This book represents a valuable source of information not only for researchers working on this subject, but also for scientists interested in fundamental aspects of cell and energy metabolism.

Book Description
Mineralizing Vesicles: From Biochemical and Biophysical Properties to Their Roles in Physiology and Disease presents the state-of-the art in the properties of mineralizing EVs and their potential clinical applications. The first chapter presents foundational biochemical and biological aspects of EVs. Next, the title coves the role of EVs in bone ossification and in cardiovascular and cartilage-related diseases. Considering the unique ability of this class of EVs to form apatite minerals assigned to their special biochemical machinery, three chapters of the book then focus on the enzymes catalysing the inorganic phosphate and calcium turn-over and the dynamic properties of the vesicles' peripheral proteins. Chapters describe the role of inorganic phosphate and calcium ions and of autophagy on the biogenesis and function of mineralizing EVs. Recent studies show that the lumen of mineralizing EVs is partially filled with miRNA, and a chapter therefore considers research on the possible function of these vesicles as signalosomes. The final five chapters of the book describe practical aspects of working with mineralizing EVs, including their purification, proteomic and biophysical analyses, the use of biomimetic models and mineralizing EVs in regenerative medicine. This title presents, for the first time, a comprehensive account of mineralizing EVs and their potential clinical applications. It will be invaluable to researchers in the field. • Covers all aspects of mineralizing EVs, from their composition to their function in physiological and pathological processes, and their clinical potential• Presents mineralizing EVs systematically using clear accessible language• Describes practical aspects of working with mineralizing EVs• Integrates an account of the biochemistry and biophysics of vesicles with their functions• Takes a multidisciplinary perspective, offering an exhaustive and cutting-edge account of mineralizing EVs and human health

Book Description
Organophosphorus Chemistry: A Practical Approach in Chemistry provides a practical introduction to the field by mixing a brief review of the subject area with key experimental details and sample procedures. Phosphorus is an element that has been central to the development of our modern way of life. Its chemistry plays a key role in the development of such important areas as pharmaceuticals, agrochemicals, modern materials and molecular biology. Much of this work requires a sound understanding of the organic chemistry of phosphorus and this volume is designed to instruct the reader in the essential methodology used. Topics covered include phosphines, applications of phosphorus (III) and (V) compounds as reagents in synthesis, the chemistry of phosphorus ylides, applications of the Wittig reaction in the synthesis of heterocyclic and carbocyclic compounds, preparation of Iminophosphoranes and their synthetic applications in the aza-Wittig reaction, phospho-transfer processes leading to [P-C] bond formation, low valent phosphorus compounds and phosphorus methods in oligonucleotide chemistry. It is intended not only for the specialist in organophosphorus chemistry, but also for the organic chemist with little experience in the field who wishes to add phophorus-based techniques to his or her ensemble of synthetic methods.
