Provides a high level reference source for scientists engaged in any aspect of plant research - chemistry, biochemistry or physiology - with primary focus on the chemistry of phosphorus-containing compounds that occur naturally in the plant kingdom, and specifically in the higher plants (Plantae). The book is comprehensive with respect to nomenclature, physical properties, and distribution worldwide. There are many tables of actual data on phosphorus compounds occurring in whole plants and parts of plants. The tables provide detailed data that is needed by the food industry, agriculture, etc as many of the phosphorus compounds are common to both plants and animals. Two appendices cover other aspects including changes in phosphorus-containing compounds during germination and their accumulation during growth and senescence. The final sections of the book comprise separate indexes of plants, compounds and authors. - Comprehensive examination of phosphorus compounds found in plants - Extensive tables listing types of compounds and their occurrence in plants including: Nomenclature; Occurrence; Physical Properties; Synthesis; Hydrolysis; Phosphorylation; Extraction; Separation and Analysis - Easy to use indexes of plants, compounds and authors

Laboratory Assessment of Vitamin Status provides a comprehensive understanding of the limitations of commonly used approaches used for the evaluation of vitamin status, reducing harm in the general health setting. It outlines the application of 'Best Practice' approaches to the evaluation of vitamin status, giving physicians and other healthcare professionals the opportunity to make evidence-based interventions. Nearly every metabolic and developmental pathway in the human body has a dependency on at least one micronutrient. Currently, the clinical utility of approaches taken by laboratories for the assessment of vitamin status is generally poorly understood, missing the opportunity to diagnosis vitamin deficiencies. This essential reference gives clinical and biomedical scientists an understanding of the limitations of commonly used approaches to the evaluation of vitamin status in the general health setting through change in practice. Nutritionists and dietitians gain an understanding of more sophisticated markers of vitamin status. - Describes specialist assays in sufficient detail to enable laboratories to replicate what is being performed by expert groups - Provides detailed information that supports laboratories in the setting up of methods for the evaluation of vitamin status - Informs laboratories looking for third party providers of specialist investigations - Provides an essential overview of reference ranges for each vitamin

The Chemistry and Biology of Nitroxyl (HNO) provides first-of-its-kind coverage of the intriguing biologically active molecule called nitroxyl, or azanone per IUPAC nomenclature, which has been traditionally elusive due to its intrinsically high reactivity. This useful resource provides the scientific basis to understand the chemistry, biology, and technical aspects needed to deal with HNO. Building on two decades of nitric oxide and nitroxyl research, the editors and authors have created an indispensable guide for investigators across a wide variety of areas of chemistry (inorganic, organic, organometallic, biochemistry, physical, and analytical); biology (molecular, cellular, physiological, and enzymology); pharmacy; and medicine. This book begins by exploring the unique molecule's structure and reactivity, including important reactions with small molecules, thiols, porphyrins, and key proteins, before discussing chemical and biological sources of nitroxyl. Advanced chapters discuss methods for both trapping and detecting nitroxyl by spectroscopy, electrochemistry, and fluorescent inorganic cellular probing. Expanding on the compound's foundational chemistry, this book then explores its molecular physiology to offer insight into its biological implications, pharmacological effects, and practical issues. - Presents the first book on HNO (nitroxyl or azanone), an increasingly important molecule in biochemistry and pharmaceutical research - Provides a valuable coverage of HNO's chemical structure and significant reactions, including practical guidance on working with this highly reactive molecule - Contains high quality content from recognized experts in both industry and academia
