Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 1994. Vitamins are essential micronutrients available to animal organisms through the diet. This book takes a fresh approach to vitamin-binding proteins, with emphasis on the nature of the binding of the vitamin ligand to a protein and its sequela. The role of vitamin-binding proteins as initiators of the metabolic response is evaluated. Experts in the field from around the world present an account of their work on the interaction of vitamins with specific intracellular systems through the appropriate binding proteins and how this interaction results in the biological action of vitamins. The book will be of interest to research workers and postgraduate students in the field of biochemistry and nutrition.

This book was released on 2008-12-16 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of ferrocene and the sandwich-type complexes, the development of organometallic chemistry took its course like an avalanche and became one of the scientific success stories of the second half of the twentieth century. Based on this development, the traditional boundaries between inorganic and organic chemistry gradually disappeared and a rebirth of the nowadays highly important field of homogeneous catalysis occurred. It is fair to say that despite the fact that the key discovery, which sparked it all off, was made more than 50 years ago, organometallic chemistry remains a young and lively discipline.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Dietary Reference Intakes for Thiamin, Riboflavin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid, Biotin, and Choline written by Institute of Medicine and published by National Academies Press. This book was released on 2000-07-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1941, Recommended Dietary Allowances (RDAs) has been recognized as the most authoritative source of information on nutrient levels for healthy people. Since publication of the 10th edition in 1989, there has been rising awareness of the impact of nutrition on chronic disease. In light of new research findings and a growing public focus on nutrition and health, the expert panel responsible for formulation RDAs reviewed and expanded its approachâ€"the result: Dietary Reference Intakes. This new series of references greatly extends the scope and application of previous nutrient guidelines. For each nutrient the book presents what is known about how the nutrient functions in the human body, what the best method is to determine its requirements, which factors (caffeine or exercise, for example) may affect how it works, and how the nutrient may be related to chronic disease. This volume of the series presents information about thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. Based on analysis of nutrient metabolism in humans and data on intakes in the U.S. population, the committee recommends intakes for each age groupâ€"from the first days of life through childhood, sexual maturity, midlife, and the later years. Recommendations for pregnancy and lactation also are made, and the book identifies when intake of a nutrient may be too much. Representing a new paradigm for the nutrition community, Dietary Reference Intakes encompasses: Estimated Average Requirements (EARs). These are used to set Recommended Dietary Allowances. Recommended Dietary Allowances (RDAs). Intakes that meet the RDA are likely to meet the nutrient requirement of nearly all individuals in a life-stage and gender group. Adequate Intakes (AIs). These are used instead of RDAs when an EAR cannot be calculated. Both the RDA and the AI may be used as goals for individual intake. Tolerable Upper Intake Levels (ULs). Intakes below the UL are unlikely to pose risks of adverse health effects in healthy people. This new framework encompasses both essential nutrients and other food components thought to pay a role in health, such as dietary fiber. It incorporates functional endpoints and examines the relationship between dose and response in determining adequacy and the hazards of excess intake for each nutrient.

This book was released on 2002-07-19 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Download or read book Template Synthesis of Macrocyclic Compounds written by N. V. Gerbeleu and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis of macrocycles is an art in itself. Template-controlled synthesis provides elegant access to fascinating macrocyclic structures. Polyazamacrocycles, crown ethers, cryptands, rotaxanes, knots -- the range of macrocyclic compounds is as broad as their potential application as molecular switches, in ion exchange, electron transfer or catalysis. This book provides authoritative information on all aspects of template-controlled macrocyclizations. It covers in depth the current state of research on template processes - novel synthetic techniques and mechanistic approaches. The critical discussion of the diverse synthetic routes includes the detailed characterization of the broad variety of macrocyclic products. References to applications of macrocyclic compounds and over 1,500 citations make this handbook an indispensable tool for chemists in academia and industry. Researchers in organic and supramolecular chemistry, biotechnology, and inorganic chemistry will find inspiration for the design, synthesis, and myriad uses of new synthetic macrocycles.
