Download or read book Dietary Reference Intakes for Vitamin C Vitamin E Selenium and Carotenoids written by Institute of Medicine and published by National Academies Press. This book was released on 2000-08-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.
Download or read book The Flavonoids written by J. B. Harborne and published by Springer. This book was released on 2013-11-11 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major purpose ofthis third volume in The Flavonoidsseries is to provide a detailed review of progress in the field during the five years, 1981-1985 inclusive. It thus continues the comprehensive coverage of the literature on these fascinating and important plant pigments which began in 1975 with the publication of The Flavonoids and which was followed in 1982 with The Flavonoids: Advances in Research. As with the two previous vo1umes, this one is entire1y se1f-contained and where necessary tabu1ar data and references from earlier vo1umes are included and expanded here. A unique feature is the complete listing in the Appendix ofall known flavonoids, which now number over 4000 structures; in this list, structures newly reported during the period 1981-1985 are so indicated. The first ten chaptersofthis book provide a critical review ofthe new substancesthat have been discovered among each of the main classes of flavonoid during the period under review. Again, the numberofnew isoflavonoids reported outweighs that ofother classesand ahundred pagesare needed to describe all the nove1 findings. Neoflavonoids, which were omitted in the first supplement, have been included again and a special chapter on miscellaneous flavonoids has been introduced to cope with those structures (e.g. homoisoflavonoids) which do not fit in easily anywhere else. Although there have been advances in flavonoid methodology, these have not been asspectacular as in earlier years. Hence, literature reports on new chromatographic and spectral procedures are included here in the individual chapters under the different flavonoid classes.

Download or read book The Handbook of Natural Flavonoids written by Jeffrey B. Harborne and published by . This book was released on 1999-06-18 with total page 910 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flavonoids are a large and important group of natural products derived from 'flavone'. Some flavonoids are intensely coloured, providing a spectrum of colours from red to blue in flowers, fruit and leaves. Other flavonoids are essentially colourless, producing the 'whiteness' of white flowers. Besides their contribution to plant colour, flavonoids have a variety of other roles in the growth and development of plants. Leaf flavonoids provide protection from the potential damage of UVB radiation. Certain flavanones are formed as antifungal barriers in plant leaves in response to microbial infection and others play an important part in plant reproduction. Flavonoids also exhibit a wide range of biological properties including anti-microbial, insecticidal and oestrogenic activities. Edited by one of the world's acknowledged leading researchers in flavonoid chemistry and biochemistry, this book is the essential guide to the chemical structure and function of all known flavonoids and contains full references, CAS numbers, chemical structures, molecular formulae and several extensive indexes. The Handbook of Natural Flavonoids is the definitive reference to this large and important group of natural products for researchers in pharmaceutical and medicinal chemistry, plant biochemistry and organic chemistry.
Download or read book Flavonoids written by José Justino and published by BoD – Books on Demand. This book was released on 2017-08-23 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flavonoids are abundant secondary metabolites found in plants and fungi that have various roles in these organisms, including pigmentation, cell signalling, plant defence and inter-organism communication. Due to their abundance in nature, flavonoids are also important components of the human diet, and the last four decades have seen an intense study focused on the structure characterization of flavonoids and on their roles in mammal metabolism. This book reviews most of the well-established activities of flavonoids, and we also present more recent research studies on the area of flavonoids, including the chemical aspects of structure characterization of flavonoids, the biosynthesis of flavonoids in model plants as well as their role in abiotic stress situations and in agriculture, the role of flavonoids in metabolism and health and their importance in foods, from consumption to their use as bioactive components.
Download or read book The Flavonoids written by Jeffrey B. Harborne and published by Springer. This book was released on 2013-11-11 with total page 1218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flavonoids, one of the most numerous and widespread groups of natural constituents, are important to man not only because they contribute to plant colour but also because many members (e.g. coumestrol, phloridzin, rotenone) are physiologically active. Nearly two thousand substances have been described and as a group they are universally distributed among vascular plants. Although the anthocyanins have an undisputed function as plant pigments, the raison d'etre for the more widely distributed colourless flavones and flavonols still remains a mystery. It is perhaps the challenge of discovering these yet undisc10sed functions which has caused the considerable resurgence of interest in flavonoids during the last decade. This book attempts to summarize progress that has been made in the study of these constituents since the first comprehensive monograph on the chemistry of the flavonoid compounds was published, under the editorship of T. A. Geissman, in 1962. The present volume is divided into three parts. The first section (Chapters 1-4) deals with advances in chemistry, the main emphasis being on spectral techniques to take into account the re cent successful applications of NMR and mass spectral measurements to structural identifications. Recent developments in isolation techniques and in synthesis are also covered in this section. Advances in chemical knowledge of individual c1asses of flavonoid are mentioned inter aha in later chapters of the book.
