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 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.

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.
