Book Description
Carotenoids are of great interest due to their essential biological functions in both plants and animals. However, the properties and functions of carotenoids in natural systems are surprisingly complex. With an emphasis on the chemical aspects of these compounds, Carotenoids: Physical, Chemical, and Biological Functions and Properties presents a b

Book Description
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.

Book Description
The Carotenoids book series provides an introduction to the fundamental chemistry, detailed accounts of the basic methods used in carotenoid research, and critical discussions of the biochemistry, functions and applications of carotenoids. Part 1 discusses the fundamental properties on which the biological functions and effects of carotenoids depend. Part 2 describes important natural functions of carotenoids in all kinds of living organisms.

Book Description
Abstract: The most important role of beta-carotene has long been thought to be the metabolic cleavage at the central double bond to produce two molecules of vitamin A (retinol). There is growing interest in the "eccentric cleavage" of dietary carotenoids at different double bond sites of beta-carotene to produce apocarotenals and their possible oxidation to apocarotenoic acids. However, there are no careful, quantitative analyses of the levels of these compounds in human foods and tissues, and little is known of the enzymology of their formation. This project is part of a larger effort to characterize the full family of putative metabolites of beta-carotenes and lycopene, their occurrence, and their biological significance. We are synthesizing and characterizing all of the possible aldehyde and acid metabolites of beta-carotene for use as analytical standards and for direct assay of their biological activity. Multi-step syntheses were employed to synthesize many of the molecules. Nuclear magnetic resonance spectroscopy, UV-visible spectroscopy, high performance liquid chromatography, and mass spectrometry are being used for characterization. The laboratory of Dr. Earl Harrison (Dept. of Nutrition) is currently studying the interaction of the eccentric cleavage products with the nuclear retinoic acid receptors (RARs), which are responsible for cell differentiation and aspects of the immune response. The interaction of these molecules with other nuclear receptors will be analyzed in the future. The samples will also be used as standards to quantitate the concentrations of eccentric cleavage products in biological samples. The synthesis of the molecules prepared to date will be described as well as aspects of the limited biological activity data gathered to date.

Book Description
Carotenoids are an essential component of the human diet. Bioactive by nature, they are rich in antioxidants, promote vitamin A activity and lower the development of chronic illnesses. As such they are an area of growing interest to researchers and scientists who are working to design, develop and launch new functional food products, dietary supplements and other nutritional solutions. Carotenoids: Nutrition, Analysis and Technology is an up-to-date overview of the key areas of carotenoids in nutrition, therapy and technology. In the first section, the authors present a functional food perspective, outlining the therapeutic applications of the bioactive pigments. The second part is dedicated to the spectroscopic analysis of carotenoids, providing in-depth scientific methods and real research findings. In the final section, various technological applications of carotenoids are considered, including biotechnology and future prospects. Written by international experts in the field, this comprehensive book will be of interest to food scientists and researchers, nutritionists and health food companies. It will be of particular use to anyone involved in the spectroscopic analysis of carotenoids and other related bioactives.
