Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the role of plant secondary metabolites as protective constituents in the human diet has been a growing area of research. Unlike the traditional vitamins, they are not essential for short-term wellbeing, but there is increasing evidence that modest long-term intakes can have favourable impacts on the incidence of cancers and many chronic diseases, including cardiovascular disease and type II diabetes, which are occurring in Western populations with increasing frequency. This book covers the latest science on the metabolism and potential health benefits of teas, cocoa, coffee and their extracts in the human diet. From an opening chapter tracing the origins of teas, cocoa and coffee as beverage, the book proceeds to explore the phytochemical content of coffee, cocoa and the various types of tea. The bioavailability of secondary metabolites from each of the beverages is then considered in depth, and related directly to their health benefits. Embracing the full range of tea, coffee and cocoa beverages and products, the book offers the most up-to-date and comprehensive treatment of these increasingly important dietary components. As the only book to bring together the latest information on the biochemistry and health benefits of teas, coffee and cocoa, this book is essential reading for food scientists and technologists involved in the production of tea, coffee and cocoa products. Nutritionists will value the book's health focus, while agricultural scientists working on the cultivation of these crops will prize its scope and depth of detail. It is also an important resource for all those who use functional ingredients in other products, whether they are based in industry or research.

Available in PDF, EPUB and Kindle. Book excerpt: Plant secondary metabolites have been a fertile area of chemical investigation for many years, driving the development of both analytical chemistry and of new synthetic reactions and methodologies. The subject is multi-disciplinary with chemists, biochemists and plant scientists all contributing to our current understanding. In recent years there has been an upsurge in interest from other disciplines, related to the realisation that secondary metabolites are dietary components that may have a considerable impact on human health, and to the development of gene technology that permits modulation of the contents of desirable and undesirable components. Plant Secondary Metabolites: Occurrence, Structure and Role in the Human Diet addresses this wider interest by covering the main groups of natural products from a chemical and biosynthetic perspective with illustrations of how genetic engineering can be applied to manipulate levels of secondary metabolites of economic value as well as those of potential importance in diet and health. These descriptive chapters are augmented by chapters showing where these products are found in the diet, how they are metabolised and reviewing the evidence for their beneficial bioactivity.

Download or read book Plant Environment Interaction written by Mohamed Mahgoub Azooz and published by John Wiley & Sons. This book was released on 2015-11-30 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increase in global population, urbanization and industrialization is resulting in the conversion of cultivated land into wasteland. Providing food from these limited resources to an ever-increasing population is one of the biggest challenges that present agriculturalists and plant scientists are facing. Environmental stresses make this situation even graver. Plants on which mankind is directly or indirectly dependent exhibit various mechanisms for their survival. Adaptability of the plants to changing environment is a matter of concern for plant biologists trying to reach the goal of food security. Despite the induction of several tolerance mechanisms, sensitive plants often fail to withstand these environmental extremes. Using new technological approaches has become essential and imperative. Plant-Environment Interaction: Responses and Approaches to Mitigate Stress throws light on the changing environment and the sustainability of plants under these conditions. It contains the most up-to-date research and comprehensive detailed discussions in plant physiology, climate change, agronomy and forestry, sometimes from a molecular point of view, to convey in-depth understanding of the effects of environmental stress in plants, their responses to the environment, how to mitigate the negative effects and improve yield under stress. This edited volume is written by expert plant biologists from around the world, providing invaluable knowledge to graduate and undergraduate students in plant biochemistry, food chemistry, plant physiology, molecular biology, plant biotechnology, and environmental sciences. This book updates scientists and researchers with the very latest information and sustainable methods used for stress tolerance, which will also be of considerable interest to plant based companies and institutions concerned with the campaign of food security.

This book was released on 2013-03-09 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant secondary metabolism is an economically important source of fine chemicals, such as drugs, insecticides, dyes, flavours, and fragrances. Moreover, important traits of plants such as taste, flavour, smell, colour, or resistance against pests and diseases are also related to secondary metabolites. The genetic modification of plants is feasible nowadays. What does the possibility of engineering plant secondary metabolite pathways mean? In this book, firstly a general introduction is given on plant secondary metabolism, followed by an overview of the possible approaches that could be used to alter secondary metabolite pathways. In a series of chapters from various authorities in the field, an overview is given of the state of the art for important groups of secondary metabolites. No books have been published on this topic so far. This book will thus be a unique source of information for all those involved with plants as chemical factories of fine chemicals and those involved with the quality of food and ornamental plants. It will be useful in teaching graduate courses in the field of metabolic engineering in plants.
Download or read book Secondary Metabolism in Microorganisms Plants and Animals written by M. Luckner and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the reactions and compounds involved in metabolism are almost identical in the different groups of living organisms. They are known as primary metabolic reactions and primary metabolic products. In addition, however, a wide variety of biochemical pathways are characteristic of only a few species of organisms, of single "chemical races" or even of a certain stage of differentiation of special ized cells. Such pathways are collectively referred to as "secondary metabolism", and the compounds formed are called "secondary products". Secondary products are frequently revealed by their color, smell, or taste. They are responsible for the flavor of most foodstuffs and beverages and for the color and fragrance of flowers and fruits. Many of them are part of the materia medica, e. g. , alkaloids, cardiac glycosides, antibiotics, or compounds acting as hormones. Others are used by industry, e. g. , rubber, tannins, and cellulose. This book treats the organization and significance of biosynthesis, storage, transformation, and degradation of the most important groups of secondary products in microorganisms, plants, and animals. It shows that the formation of secondary products is a common characteristic of specialized cells brought about by the action of special enzymes encoded by specific genetic material. It demon strates that the. biosynthesis of secondary products is typically without signifi cance for the individual producer cell, but may play a decisive role in the develop· ment and function of the producer organism as a whole.

This book was released on 2019-08-06 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Literature Review from the year 2018 in the subject Chemistry - Bio-chemistry, grade: 3.5, Lagos State University, course: Biochemistry, language: English, abstract: Since recent history, there have been tremendous efforts in combating the challenges of food insecurity. This mini-review discusses how environmental conditions favour or impair the growth and survival of plants via the molecular mechanisms of the secondary metabolites. Like animals, plants have survived many eons by evolving adaptive mechanisms in the presence of the myriad of abiotic and biotic stressors. In this text, the subject of drought and salt content in relationship to their role in biosynthesis of secondary metabolites is being discussed. Fundamentally, plants require optimum concentrations of microfauna/ micronutrients and favourable climatic/edaphic conditions in their metabolism. Consequently, they produce primary metabolites (such as carbohydrates, amino acids among others) that are needed for the normal growth and reproduction of plants. On the other hand, the secondary metabolites are mostly needed for ecological functions and regulating the primary metabolic pathways. Plants via their diverse pathways (TCA cycle, MEP pathway, shikimic pathway, mevalonate pathways) have been found to produce secondary metabolites such as terpenes, phenolic and nitrogen-based compounds. These secondary metabolites have been linked to affect crop yield and medicinal properties of plants in addition to other applications. Through well-controlled machinery of signal transduction; in response to ionic and osmotic balances, the biosynthesis of secondary metabolites has been known to be induced or inhibited for the growth and survival of the plant species.
Download or read book Primary and Secondary Metabolism of Plants and Cell Cultures III written by J. Schripsema and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1984 and 1988, when meetings were held on the topic of primary and secondary metabolism of plant cell cultures, there has been a clear shift of the focus of ongoing research. While the cell culture itself and the production of secondary metabolites and the biosynthetic pathways and the activity of enzymes were major topics, now these aspects are linked with genes, i.e. molecular biology becomes more prominent. This state-of-the-art book has contributions on such subjects as fermentation, enzymology of secondary metabolism, catabolism of secondary metabolites, elicitation of pathways and genetic modification of metabolic pathways. It includes contributions on the most recent achievements in the research on among other things tropane and indole alkaloids, phenolics, (iso)flavonoids, terpenes and cardenolides. It is an excellent review of the progress made in the past years and a perspective on the future developments.
Download or read book The Biosynthesis of Secondary Metabolites written by R. B. Herbert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about experiments and results of experiments. The results described are the fruit of thirty years' labour in the field of secondary metabolism. Secondary metabolism, more than any other part of the chemistry of life, has been the special preserve of organic chemists. Investiga tion of secondary metabolism began with curiosity about the struc tures of compounds isolated from natural sources, i.e. secondary metabolites. Coeval with structure determination there has been a curiosity about the origins and mechanism of formation of secondary metabolites (or natural products as they have been called). It is the experimental outcome of this curiosity that is described here. This account is primarily intended to be an introduction to the biosynthesis of secondary metabolites. I have also endeavoured, however, to make the book as comprehensive as possIble. This has meant that some of the material has had to be presented in abbrevi ated form. The abbreviated material is largely confined to particular sections of the book. The paragraphs marked with a dagger (t) can be omitted by the reader wishing to acquire a general introduction to the subject. A blend of the most significant and the most recent references is cited to provide the reader with ready access to the primary litera ture. This is clearly most necessary for the material presented in abbreviated form. Relevant reviews are also cited.
Download or read book Secondary Metabolism and Cell Differentiation written by M. Luckner and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. Secondary Metabolism and Differentiation In addition to the primary metabolic reactions, which are similar in all living beings (formation and breakdown of nucleic acids and proteins as well as of their precursors, of most carbohy drates, of some carboxylic acids, etc. ), a vast number of metab olic pathways lead to the formation of compounds peculiar to a few species or even to a single chemical race only. These reac tions, in accord with CZAPEK (1921) and PAECH (1950), are summed up under the term "secondary metabolism", and their products are called "secondary metabolites. " The wide variety of secondary products formed in nature includes such well-known groups as alkaloids, antibiotics, cardiac glyco sides, tannins, saponins, volatile oils, and others. A consider able number of them are of economic importance in therapeutics or technology. Although secondary products are produced by micro organisms, higher plants, and animals (cf. LUCKNER, 1972), most of the substances are found in the plant kingdom. The lack of mechanisms for true excretion in higher plants may result in this unequal distribution, the "waste products" of metabolism in plants instead being accumulated in the vacuoles, the cell walls, or in special excretory cells or spaces of the organism ("metabolic excretion," cf. FREY-WYSSLING, 1935, 1970; MOTHES, 1966a, b, 1972; LUCKNER et al. , 1976. Many secondary substances have, however, a direct biologic func tion. They can be regulatory effectors, e. g.
