Download or read book Laboratory Assessment of Vitamin Status written by Dominic J. Harrington and published by Academic Press. This book was released on 2018-11-28 with total page 340 pages. 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 Industrial Biotechnology of Vitamins Biopigments and Antioxidants written by Erick J. Vandamme and published by John Wiley & Sons. This book was released on 2016-04-25 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamins are a group of physiologically very important, chemically quite complex organic compounds, that are essential for humans and animals. Some vitamins and other growth factors behave as antioxidants, while some can be considered as biopigments. As their chemical synthesis is laborious, their biotechnology-based synthesis and production via microbial fermentation has gained substantial interest within the last decades. Recent progress in microbial genetics and in metabolic engineering and implementation of innovative bioprocess technology has led to a biotechnology-based industrial production of many vitamins and related compounds. Divided into three sections, this volume covers: 1. water-soluble vitamins 2. fat-soluble vitamin compounds and 3. other growth factors, biopigments, and antioxidants. They are all reviewed systematically: from natural occurrence and assays, via biosynthesis, strain development, to industrially-employed biotechnological syntheses and applications.

Download or read book Digestive Physiology and Metabolism in Ruminants written by Y. Ruckebusch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

Download or read book Tetrapyrroles written by Martin Warren and published by Springer Science & Business Media. This book was released on 2009-12-21 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Informative and unique, Pocket Handbook of GI Pharmacotherapeutics is a must have reference for any internist, gastroenterologist or general practioner who endeavors to provide better treatment of their patients.

Download or read book Introduction to Enzyme and Coenzyme Chemistry written by T. D. H. Bugg and published by John Wiley & Sons. This book was released on 2012-05-29 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes are giant macromolecules which catalyse biochemical reactions. They are remarkable in many ways. Their three-dimensional structures are highly complex, yet they are formed by spontaneous folding of a linear polypeptide chain. Their catalytic properties are far more impressive than synthetic catalysts which operate under more extreme conditions. Each enzyme catalyses a single chemical reaction on a particular chemical substrate with very high enantioselectivity and enantiospecificity at rates which approach “catalytic perfection”. Living cells are capable of carrying out a huge repertoire of enzyme-catalysed chemical reactions, some of which have little or no precedent in organic chemistry. The popular textbook Introduction to Enzyme and Coenzyme Chemistry has been thoroughly updated to include information on the most recent advances in our understanding of enzyme action, with additional recent examples from the literature used to illustrate key points. A major new feature is the inclusion of two-colour figures, and the addition of over 40 new figures of the active sites of enzymes discussed in the text, in order to illustrate the interplay between enzyme structure and function. This new edition provides a concise but comprehensive account from the perspective of organic chemistry, what enzymes are, how they work, and how they catalyse many of the major classes of enzymatic reactions, and will continue to prove invaluable to both undergraduate and postgraduate students of organic, bio-organic and medicinal chemistry, chemical biology, biochemistry and biotechnology.
