Book Description
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

Book Description
The Organic Chemistry of Enzyme-Catalyzed Reactions is not a book on enzymes, but rather a book on the general mechanisms involved in chemical reactions involving enzymes. An enzyme is a protein molecule in a plant or animal that causes specific reactions without itself being permanently altered or destroyed. This is a revised edition of a very successful book, which appeals to both academic and industrial markets. - Illustrates the organic mechanism associated with each enzyme-catalyzed reaction - Makes the connection between organic reaction mechanisms and enzyme mechanisms - Compiles the latest information about molecular mechanisms of enzyme reactions - Accompanied by clearly drawn structures, schemes, and figures - Includes an extensive bibliography on enzyme mechanisms covering the last 30 years - Explains how enzymes can accelerate the rates of chemical reactions with high specificity - Provides approaches to the design of inhibitors of enzyme-catalyzed reactions - Categorizes the cofactors that are appropriate for catalyzing different classes of reactions - Shows how chemical enzyme models are used for mechanistic studies - Describes catalytic antibody design and mechanism - Includes problem sets and solutions for each chapter - Written in an informal and didactic style

Book Description
Excluding the biological polymers proteins, lipids and nucleic acids, modified tetrapyrroles are the biological molecules that have had the greatest impact on the evolution of life over the past 4 billion years. They are involved in a wide variety of fundamental processes that underpin central primary metabolism in all kingdoms of life, from photosynthesis to methanogenesis. Moreover, they bring colour into the world and it is for this reason that these compounds have been appropriately dubbed the ‘pigments of life’. To understand how and why these molecules have been so universally integrated into the life processes one has to appreciate the chemical properties of the tetrapyrrole scaffold and, where appropriate, the chemical characteristics of the centrally chelated metal ion. This book addresses why these molecules are employed in Nature, how they are made and what happens to them after they have finished their usefulness.

Book Description
Explaining the practical implications of new discoveries in 'life-course biology', Nutrition and Lifestyle for Pregnancy and Breastfeeding is an informed resource on factors that affect offspring development. The impact of parental lifestyle and behavioural choices influence not only fetal development and birth outcomes, but also postnatal development, yet guidance on appropriate diet, behaviour, and exposures during pregnancy is often confusing and contradictory. With accessible explanations of the latest scientific research, and clear summaries and recommendations, this book is a valuable and authoritative guide for all levels of health care providers. The authors provide an overview of the background evidence, highlighting the importance of lifestyle choices prior to and during pregnancy. In-depth discussions of nutritional and lifestyle factors that impact on pregnancy and offspring outcomes are based on the latest research and exploration of key scientific studies. Nutrition and Lifestyle for Pregnancy and Breastfeeding is a manual offering both scientific and clinical evidence to empower health care providers and ensure they have the information necessary to confidently care for prospective and new parents.
