Описание: As in other scientific fields, the importance of boundary areas in wood research, such as that between lignin chemistry and hemicellulose chemis- try, continues to increase. Although the utilization of individual wood components has advanced to an appreciable extent, research into oligo- merie or polymerie compounds of two or more different components has made little progress. By contrast, in other fields, glycoproteins and pro te- oglycans have been found to form biochemical active centers in enzymes and microbes. The association between lignin and carbohydrates in lignified plants was first recognized in 1866. However, research has advanced slowly because of difficulty in the isolation and determination of wood glycocon- jugates, whieh likely have an important influence on the formation of wood, pulping behavior, pulp quality and digestibility by ruminants. Most plants contain both hydrophilie polysaccharides and hydrophobie lignins in their tissues. Lignins have been recognized to not only give mechanieal strength or rigidity to a tree or wood, but also to prevent invasion by fungi, and provide cell wall material, especially in the tracheids and vessels that deliver water extracted from the soil to the top of woody plants. How- ever, in trees, lignins have been found to interact with the polysaccharides, partieularly hemicelluloses, with whieh they coexist, leading to the forma- tion of another chemical component, a kind of glycoconjugate. Therefore, it is necessary to inc1ude lignin or p-hydroxycinnamie acids in any discus- sion on wood hemieelluloses.

Описание: The Molecular Nutrition of Fats presents the nutritional and molecular aspects of fats by assessing their dietary components, their structural and metabolic effects on the cell, and their role in health and disease. Subject areas include molecular mechanisms, membranes, polymorphisms, SNPs, genomic wide analysis, genotypes, gene expression, genetic modifications and other aspects. The book is divided into three sections, providing information on the general and introductory aspects, the molecular biology of the cell, and the genetic machinery and its function. Topics discussed include lipid-related molecules, dietary lipids and lipid metabolism, high fat diets, choline, cholesterol, membranes, trans-and saturated fatty acids, and lipid rafts. . Other sections provide comprehensive discussions on G protein-coupled receptors, micro RNA, transcriptomics, transcriptional factors, cholesterol, triacylglycerols, beta-oxidation, cholesteryl ester transfer, beta-oxidation, lysosomes, lipid droplets, insulin mTOR signaling and ligands, and more.

Описание:
Molecular Basis of Nutrition and Aging: A Volume in the Molecular Nutrition Series focuses on the nutritional issues associated with aging and the important metabolic consequences of diet, nutrition, and health. The book is subdivided into four parts that reflect the impact of nutrition from a biomolecular level to individual health.
In Part One, chapters explore the general aspects of aging, aging phenotypes, and relevant aspects of nutrition related to the elderly and healthy aging. Part Two includes molecular and cellular targets of nutrition in aging, with chapters exploring lipid peroxidation, inflammaging, anabolic and catabolic signaling, epigenetics, DNA damage and repair, redox homeostasis, and insulin sensitivity, among others.
Part Three looks at system-level and organ targets of nutrition in aging, including a variety of tissues, systems, and diseases, such as immune function, the cardiovascular system, the brain and dementia, muscle, bone, lung, and many others. Finally, Part Four focuses on the health effects of specific dietary compounds and dietary interventions in aging, including vitamin D, retinol, curcumin, folate, iron, potassium, calcium, magnesium, zinc, copper, selenium, iodine, vitamin B, fish oil, vitamin E, resveratrol, polyphenols, vegetables, and fruit, as well as the current nutritional recommendations.

Описание:
The Molecular Nutrition of Amino Acids and Proteins provides an in-depth look at the involvement and role of amino acids and proteins in molecular nutrition. Editor Dominique Dardevet has assembled a collection of chapters written by leading researchers and top professors that provide the reader with a comprehensive understanding of amino acids and proteins.
The book provides an introduction to the fundamentals of amino acids and proteins as well as the composition of food. It then delves into the molecular biology of the cell and genetic machinery and its function. The Molecular Nutrition of Amino Acids and Proteins also features reference guides for terms and bullet-point summaries, making it readily accessible to novices while still providing the most up-to-date and detailed information that experienced researchers need.

Описание: . Molecular Aspects of Alcohol and Nutrition is a valuable resource for nutrition researchers and nutritionists who study or treat alcohol-related diseases. Experts from across the field of alcohol research explain how alcohol disrupts normal fat, carbohydrate, and protein metabolic processes occurring in the liver as well as other parts of the body. . The book discusses how this can lead to alcoholic liver disease (ALD) as well as contribute to the onset of Type 2 diabetes and the metabolic syndrome. It also explores how alcohol affects nutrient absorption in the gastrointestinal tract and can lead to anemia and reduced amounts of fat soluble vitamins. . This book explores both the primary and secondary consequences of alcohol consumption. Chapters in the first section investigate the basic science of alcohol metabolism – focusing on how alcohol and its toxic metabolites disrupt and impair normal nutrient regulation at the molecular level. Further chapters explore how alcohol affects many extra-hepatic organs and tissues as well as the secondary consequences of alcohol consumption such as reduced levels of minerals like magnesium, calcium, and trace elements like zinc.
