Download or read book Nutritional and Toxicological Significance of Enzyme Inhibitors in Foods written by Mendel Friedman and published by Springer. This book was released on 1986-10-31 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean protei ns are wi de 1 y used inhuman foods ina vari ety of forms, including baby formulas, flour, soy protein concentrates, soy protein isolates, soy sauces, textured soy fibers, and tofu. The presence of inhibitors of digestive enzymes in soy proteins impairs nutritional quality and possible safety of this impportant legume. Normal processing conditions based on the use of heat do not completely inactivate these inhibitors, so that residual amounts of plant protease inhibitors are consumed by animals and man. Inhibitors of digestive enzymes are present not only in legumes, such as soybeans, lima beans, and kidney beans, but also in nearly all plant foods, including cereals and potatoes, albeit in much smaller amounts. The antinutritional effects of inhibitors of proteolytic enzymes have been widely studied and can be ameliorated by processing and/or sulfur amino acid fortification. A more urgent concern is reports that rats fed diets containing even low levels of soybean-derived inhibitors, which are found in foods such as soy-based baby formulas, may develop over their lifespan pancreatic lesions leading eventually to neoplasia or tumor formation. On the other hand, recent stUdies suggest that certain enzyme inhibitors from plant foods may prevent cancer formation in other tissues. A key question, therefore, is whether inhibitors from plant foods constitute a human health hazard.

It is important to know the methods of extracting molecules, the biosynthesis routes, and their relationship with activities that can benefit from their consumption. Therefore, the book includes chapters that provide information on extraction and optimization techniques, biosynthetic pathways, and the identification and characterization of miRNAs involved in the regulation of their biosynthesis.
Download or read book Enzymatic polymerization of phenolic compounds by oxidoreductases written by Mohamed Ghoul and published by Springer Science & Business Media. This book was released on 2012-02-06 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enzymatic polymerization of phenolic compounds has been generating interest in several fields such as food, cosmetics, and pharmaceuticals. These compounds are employed for their antioxidant properties; however, their use is limited by their low solubility and thermal stability. Polymerization can improve their solubility and their thermal stability though and create new properties which are dependent on the molecular mass and the structure of polymers. The reaction yield, the polydispersity, the molecular mass, the structure and the properties of synthesized polymers can be controlled by the mode of control of the reaction and by the reaction conditions. Enzymatic polymerization of phenolic compounds by oxidoreductases analyze the processes used and the key factors (temperature, solvent, origin of the enzyme, structure of the substrate, reactor design, ...) which control the polymerization of phenolic species by these oxidoreductase enzymes in order to obtain polymers with desired characteristics and properties.

Download or read book Plant Polyphenols written by Richard W. Hemingway and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1027 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference.
Download or read book Plant Secondary Metabolites written by Alan Crozier and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 384 pages. 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.
