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 Eccentric Cleavage Products of Beta Carotene written by Damian P. Hruszkewycz and published by . This book was released on 2009 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Carotenoids in Nature written by Claudia Stange and published by Springer. This book was released on 2016-08-02 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Expression of Carotenoid Cleavage Dioxygenases 1, 4a, and 4b in Berries of Vitis Vinifera Throughout Ripening and in Vitro Substrate Specificity written by Yi-Chia Lin and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Carotenoid cleavage dioxygenases (CCDs) are a group of enzymes that participate in carotenoid catabolism, with CCD1 and CCD4 involved in norisoprenoid production. Norisoprenoids, breakdown products of carotenoids, are volatile compounds with low sensory thresholds contributing to the aroma of flowers and fruits, including grape Vitis vinifera. Due to the uneven ripening nature of grape berries, a mean value of pooled samples on a given day may not reflect such variation. A single berry approach was performed to relate the gene expression of VvCCD1, VvCCD4a, and VvCCD4b with the firmness of grape berries, making a direct linkage between gene expressions of one berry to the firmness measurement of that berry. VvCCD1 and VvCCD4b gene expression were found to be negatively correlated with firmness under certain conditions, while VvCCD4a expression did not correlate with firmness. A series of carotenoid-producing Escherichia coli cell lines were used to reveal the substrate specificity of VvCCD1, VvCCD4a, and VvCCD4b in vitro. In this study, VvCCD1 showed cleaving activity at the 9-10 (9'-10') carbon position towards cyclic ends of [beta]-carotene, [delta]-carotene, [epsilon]-carotene, and [alpha]-zeacarotene. VvCCD1 also showed 5'-6' carbon position cleaving activity towards the acyclic end for [delta]-carotene, while for [alpha]-zeacarotene the cleaving activity to the acyclic end was found towards both the 5'-6' and 9'-10' carbon positions. Of the carotenoids tested, VvCCD4b was found only capable of cleaving [alpha]-zeacarotene at the 9-10 carbon position, while VvCCD4a did not utilize any of the substrates tested.

It intends to give a broad but concise overview of the various aspects of apocarotenoid biosynthesis in Crocus sativus, its regulation and pharmacology . Crocus sativus L. of family Iridaceae is an important medicinal plant. The dried stigma of C. sativus flower is considered as the world's costliest spice. Saffron is the sources of unique carotenoid derived molecules called apocarotenoids which include crocin, crocetin, picrocrocin and safranal. These molecules are synthesized in the tissue and developmental stage specific manner. Besides providing colour, aroma and flavour to the spice, these molecules have tremendous medicinal importance. The book uncovers major concepts of apocarotenoids biosynthesis and provides deeper and more complete understanding about their biotechnological and pharmacological applications. The book is divided into three sections – The first section provides a general introduction of C. sativus, its apocarotenoids, their biosynthesis, regulation and transport. Second section provides information about the carotenoid cleavage dioxygenases (CCDs) which are the key players in apocarotenoid biosynthesis. The classification of plant CCDs, their structure, reaction mechanism, biotechnological application are thoroughly discussed. The final section deals with the major pharmacological properties of C. sativus apocarotenoids, ranging from their role as anticancer to their utility as neuroprotective molecules. This is a one of its kind book on Crocus sativus. It will be useful for the researchers working on Crocus sativus, students and also practitioners involved in extraction and bio-synthesis of the useful medical components.
