Carotenoids: Structure and Function in the Human Body


Book Description

Plants produce chemicals as part of their normal metabolic activities. These include primary metabolites found in all plants, such as sugars and fats, as well as secondary metabolites, which can have therapeutic effects in humans and be refined to produce drugs. Plants synthesize a bewildering variety of phytochemicals, but most are derivatives of a few biochemical motifs. Numerous herbal-derived substances have been evaluated for their therapeutic potential. These include alkaloids, coumarins, saponins, plant pigments and flavonoids. Flavonoids, carotenoids and anthocyanins are probably the best known of these substances due to their antioxidant properties. Carotenoids: Structure and Function in the Human Body presents comprehensive coverage of carotenoids. The text covers the scientific literature and clinical significance of this organic pigment, with an emphasis on its therapeutic potential. The authors approach carotenoids from a range of perspectives, from their structural and physicochemical properties to their distribution in nature, interaction with the human metabolism, and use as a coloring agent in various products. The intake, metabolism and secretion of anthocyanins in the human body are covered in-depth, as are the biosynthetic pathways through which these compounds are synthesized in the natural system. Factors affecting stability and extraction are listed, and health-related uses and biological activities are covered in great detail. Present and future trends in carotenoid research are also presented. This book provides a solid background in carotenoids for researchers and professionals in food science, food technology, nutrition, biology, chemistry and medical sciences.

Dietary Reference Intakes for Vitamin C, Vitamin E, Selenium, and Carotenoids


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.

Handbook of Oxidants and Antioxidants in Exercise


Book Description

Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress.The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes.This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.




Vitamins


Book Description

This single-source reference draws together the current knowledge of the vitamins’ biological properties in the context of human nutrition. Vitamins are co-enzymes, antioxidants or precursors of hormones and are therefore involved in a great many biochemical and physiological processes. They play a vital role in the maintenance of health, and there is evidence that dietary sources of vitamins have beneficial effects in the prevention of heart-related diseases, bone diseases and possibly cancer. Following introductory chapters on historical and nutritional aspects of vitamins, the next four chapters cover relevant and detailed aspects of physiology and functional anatomy, biochemistry, immunology and the regulation of protein synthesis by nuclear hormone receptors. These background chapters, supported by a glossary of terms, provide the scientific principles upon which vitamin functions are based. The following thirteen chapters deal with each vitamin in turn. Subject areas include chemical structure, intestinal absorption, transport, metabolism, biochemical and physiological actions, immunoregulatory properties, deficiency-related diseases and potential toxicity. An extensive bibliography refers the reader to the original research literature. Vitamins is aimed at nutritionists, biochemists, physiologists and physicians whether they be researchers, teachers or students. Food scientists, food technologists and many others working in the health professions will also find much of use and interest in the book. The inclusion of the theoretical principles in the background chapters makes the book an ideal starting point for those working outside the area who need a solid overview of the subject.

Carotenoids in Nature


Book Description

This comprehensive, edited book explores carotenoids and their important functional roles in yeast, bacteria and plants and a profound exposition on the structures of carotenoid molecules, focusing in the first of three parts on the biosynthesis of carotenoids. The regulation of carotenoid biosynthesis in photosynthesis as well as in plant, fruits, storage roots and algae is central to the second part, and discoveries about the function of carotenoids in human health feature in the third and final part. Many helpful illustrations, explanations, overviews and examples help to bring readers up to date on relevant themes including carotenogenic genes, carotenoids in fruits and metabolic engineering. The book explores where carotenoids are synthesized in nature, including in carrots and algae. Contributing expert authors examine enzyme functions and plant models, and analyze the structure of carotenoid molecules. The function of carotenoids in photosynthesis and in photosynthetic organs as well as during fruit ripening are then explored. A whole chapter is dedicated to the latest research on apocarotenoids and further chapters cover interesting and novel themes on plastid development and the epigenetic regulation that affects carotenoid synthesis in plants. The metabolic engineering of carotenoids that has been done in fruits, plants, and seeds is another area that readers can explore, along with evidences on the function of carotenoids in human nutrition, as antioxidants, as in the control of lipid metabolism and in the absorption of carotenoids. This is a highly informative and wide-ranging work which will update researchers in the field, as well as supporting students of plant physiology and biotechnology, as supplementary reading.
