This book was released on 2012-12-06 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substances belonging to this group of organic compounds are wi,lely distributed in Nature, being found in plants, both higher and lower fungi and, upto the present time, in one animal source, sheep wool-fat. For a long time no real differentiation was possible between the tetra- and penta cyclic triterpenes and the sterols. Then the two latter became disting uishable by their selenium. ·dehydrogenation products, i. e. , picene and naphthalene derivatives from the pentacyclic triterpenes and DIELS' hydrocarbon from the sterols. It is now apparent that those compounds yielding predominantly I: 2: 8-trimethylphenanthrene on dehydro genation represent yet another class, and this property is regarded as typical of the tetracyclic triterpenes. The group contains both C and C 30 3l compounds and, although the latter fall outside RUZICKA'S strict definition of triterpenes (I42), it seems desirable to permit this deviation. Members with thirty-two carbon atoms may well be discovered in due course. In a most· valuable account of the triterpenes written in I949, JEGER. (II3) was able to summarize all that was known about the tetra cyclic group in a very small compass. Most of the work discussed in the present article has been published during the last five years and in that time the structures of some twenty compounds have been elucidated. Of outstanding importance is the revelation of close structural relation ships tQ the steroids, and the presence of C and C side-chains, skeletally 8 9 identical with those of cholesterol and ergosterol.

Download or read book Fortschritte der Chemie Organischer Naturstoffe / Progress in the Chemistry of Organic Natural Products / Progrès Dans la Chimie des Substances Organiques Naturelles written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: In agreement with SCHLENK (I78) "nucleotide" is here taken to mean a phosphoric ester of an N-glycoside of a heterocyclic base. Although they fall outside the scope of this definition, phosphorylated derivatives of riboflavin are added in recognition of their close relation to the main body of nucleotides. A complete review of even the organic chemistry of nucleotides and their derivatives would now form a substantial monograph. The smaller and less characteristic fragments of the nucleotides, namely the hetero cyclic bases, the component sugars and the derived sugar phosphates, are therefore excluded from this article. * Their chemistry is of longer standing and is covered in standard works. On the other hand knowledge of the "nucleosides", the N-glycosides of heterocyclic bases, has expanded very considerably in recent years and an account of the relevant work is therefore included. With regard to the nucleotides themselves attention is focussed on work published in the last few years leading to improved characterisation, more exact structural knowledge and increased availa biIity. Only such enzymatic experiments as bear direct1y on structural problems are discussed and therefore much fascinating work by KALCKAR, FRIEDKIN et al. and by KORN BERG has been omitted. I t would be unthinkable to present a review on nucleotides without mentioning that the foundations of the subject were laid by P. A. LEVENE. His monograph with BASS (I36) was published in 1931 and two reviews by LYTHGOE (I50, I5I) cover the intervening period until 1944.
Book Synopsis Essential Readings in Light Metals, Volume 1, Alumina and Bauxite by : Don Donaldson
Download or read book Essential Readings in Light Metals, Volume 1, Alumina and Bauxite written by Don Donaldson and published by Springer. This book was released on 2017-01-04 with total page 1168 pages. Available in PDF, EPUB and Kindle. Book excerpt: ONE OF A FOUR-BOOK COLLECTION SPOTLIGHTING CLASSIC ARTICLES Five decades of landmark original research findings and reviews Highlighting some of the most important findings reported over the past five decades, this volume features some of the best technical papers published on alumina and bauxite from 1963 to 2011. Papers have been divided into thirteen subject sections for ease of access. Each section has a brief introduction and a list of recommended articles for researchers interested in exploring each subject in greater depth. Only about fifteen percent of the alumina and bauxite papers ever published in Light Metals were chosen for this volume. Selection was based on a rigorous review process. Among the papers, readers will find landmark original research findings and expert reviews summarizing current thinking on key topics at the time of publication. From basic research to advanced applications, the articles published in this volume collectively represent our body of knowledge in alumina and bauxite. Students, scientists, and engineers should turn to this volume to discover the historical development of alumina and bauxite research as well as the current state of the science and the technology. Moreover, the papers published in this volume will serve as a springboard for future research and discoveries.
