Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1852 edition. Excerpt: ... CHAPTER XII. How rarely is it--more rarely than when, in the midst of the broad Atlantic, vessel meets vessel--that man can ask his heart, "What cheer V and receive for answer, "Alls well." When Julian Ludlow retired to his chamber that night--when the door was closed, and, by the kindly but officious care of Mr. Westwoods valet, he was hurried to bed more rapidly than he desired--he lay awake for upwards of an hour, notwithstanding the exhaustion of illness, and the unusual fatigue. The cry rose up within him--" What cheer?" But the answer never was "Alls well." At one time, it was "Breakers a-head " and at others, the same voice spoke of dangers all around. Every one has felt how different is the aspect of the same facts and circumstances at each varying hour of the day; how differently we look upon our fate and future in the merry morning, in the sunny noon, and in the dull, silent night; and there left alone, with the dim watch-lamp winking in the chimney, almost all that was bright and cheering in the events of that day passed away from Julians eyes like unreal pageants; and nothing but the dark, and the coarse, and the heavy remained. Sometimes he could hardly believe it real; that he had spoken as he had; that Mary had so answered him; that their almost insane love had been breathed to each other; that their hearts had found voice in sounds beyond recal. It seemed a dream--a vision, which could have no truth in it; and yet it came back and back upon him with an awful sense of all its consequences. Was not the love itself rash, mad, hopeless % Had not the avowal of it been wrong, base, ungrateful? "What would Mr. Westwood think--he who had loaded him with kindness--he who had fostered, with such tenderness, his youth, promoted...

Book Description
The fields of glycochemistry and glycoscience are rich and varied and where much can be learned from Nature. As Nature is not always able to produce carbohydrates in quantities useful for not only in research but also as therapeutic agents, new ways need to be found to optimize the yield. This book presents an overview of the latest developments in the field of carbohydrates, ranging from de-novo approaches via cyclodextrin chemistry to the synthesis of such highly complex glycoconjugates as glycosphingolipids and GPI anchors. The main emphasis remains on the synthetic aspects making the book an excellent source of information for those already involved in carbohydrate chemistry, as well as for those organic chemists who are beginners in this field. Equally of interest to synthetic chemists, as well as medicinal chemists and biochemists.

Book Description
A growing awareness of the relationship between diet and health has led to an increasing demand for food products that support health beyond simply providing basic nutrition. Digestive health is the largest segment of the burgeoning functional food market worldwide. Incorporation of bioactive oligosaccharides into foods can yield health benefits in the gastrointestinal tract and other parts of the body that are linked via the immune system. Because oligosaccharides can be added to a wide variety of foodstuffs, there is much interest within the food industry in incorporating these functional ingredients into healthy food products. Moreover, other areas such as pharmaceuticals, bioenergy and environmental science can exploit the physicochemical and physiological properties of bioactive oligosaccharides too. There is therefore a considerable demand for a concentrated source of information on the development and characterization of new oligosaccharides with novel and/or improved bioactivities. Food Oligosaccharides: Production, Analysis and Bioactivityis a comprehensive reference on the naturally occurring and synthesised oligosaccharides, which will enable food professionals to select and use these components in their products. It is divided into three sections: (i) Production and bioactivity of oligosaccharides, (ii) Analysis and (iii) Prebiotics in Food Formulation. The book addresses classical and advanced techniques to structurally characterize and quantitatively analyse food bioactive oligosaccharides. It also looks at practical issues faced by food industry professionals seeking to incorporate prebiotic oligosaccharides into food products, including the effects of processing on prebiotic bioavailability. This book is essential reading for food researchers and professionals, nutritionists and product developers working in the food industry, and students of Food Science with an interest in functional foods.
