Download or read book Mirror Image Asymmetry written by James P. Riehl and published by John Wiley & Sons. This book was released on 2011-04-22 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the importance and consequences of asymmetry from molecules to the macroscopic world As scientists have become more capable of probing the structure of three-dimensional objects at the molecular level, the need to understand the concept and the consequences of mirror-image asymmetry—chirality—has increased enormously. Written at an introductory level, Mirror-Image Asymmetry provides an overview of the importance and effects of asymmetry from the atomic and molecular world of physics and chemistry to the organisms and structures that we see and use in our everyday life. The reader will develop a broad appreciation of three-dimensional asymmetry from the microscopic molecular world to the macroscopic world of handedness, automobile driving, windmills, sports, and similar phenomena. The book features: An introduction to basic definitions and the nomenclature of asymmetric and dissymmetric molecules Up-to-date examples of the importance and consequences of asymmetry in modern drug applications, current theories of the origin of asymmetry in nature, and examples of molecular asymmetry in smell, taste, and insect communication Many illustrations, chemical structures, and photographs that enable the reader to connect the actual asymmetrical structures to the different phenomena that depend on structural asymmetry In the 150 years since Louis Pasteur discovered asymmetry in molecular structures, scientists have made great progress in understanding how interactions between chiral molecules influence biochemical processes. This knowledge is leading to very sophisticated asymmetric synthetic techniques that have greatly benefitted many research groups especially those in the pharmaceutical industry. This guide to the role of molecular and macroscopic chirality will inspire students and scientists in chemistry, biology, physics, and drug discovery.
Download or read book On Chirality and the Universal Asymmetry written by Georges H. Wagnière and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until half a century ago, it was assumed that the forces of nature were symmetric and that they did not distinguish between right and left, between image and mirror image. The discovery of the violation of parity in 1956 was more than a sensation, for some it was a shock. It implied that the universe displays handedness, or chirality, and that it is fundamentally asymmetric. Remarkably, a most striking asymmetry is encountered in the realm of biology. Living organisms contain proteins built almost exclusively from L-amino acids, and nucleic acids derived from D-sugars only. Yet a mirror-image biochemistry, based on D-amino acids and L-sugars is, from a purely chemical standpoint, entirely conceivable. Where, then, does this extraordinary natural selectivity come from? Is it directly, or indirectly, connected to the universal violation of parity? This book is meant as a brief review of the various manifestations of handedness, or chirality, in the universe. It does not attempt to present a solution to basic questions which perhaps will never be unambiguously and conclusively answered. Rather, it is an excursion through nature, to observe and recognize how the chirality manifests itself at different structural levels. The excursion starts in the chemistry and physics laboratory. Then a journey into outer space and back in time is undertaken. After a return to our planet Earth, the focus is on the development of living organisms. The text should be accessible to anyone having the equivalent of a first-year university instruction in physics and chemistry. It is also hoped that a layperson with a more modest scientific formation may gain a general impression of the basic asymmetry in nature and of the fundamental significance of chirality. Mathematical expressions, wherever they occur, may then be overlooked. Some more difficult sections may be skipped. A Glossary preceding the Subject Index should be helpful.

Download or read book Asymmetry in Plants written by Bir Bahadur and published by CRC Press. This book was released on 2019-03-25 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants exhibit forms of asymmetry analogous to "handedness" in bilaterally symmetrical animals. This book explores the evolutionary significance and development of asymmetry. Examples of genetic control include the direction of tendril or stem coiling of many climbing plants; the so-called spiral phyllotaxy and floral taxy; and contorted petal arrangement is another kind of left- right symmetry in plants; the direction of contortion is fixed in some but not in other plants. The book will underscore tha all phenomena related to handedness start during embryogenesis itself, with the occurrence of embryo rotation. Key selling features: First consolidated book on Plant Handedness Relates handedness, asymmetry and chirality to the evolution of different organizational levels in plant biology Emphasizes handedness as a vital governing force in plant functional evolution Provides a new perspective, hitherto ignored, into plant developemtn and evolution Describes how an age-old phenomenon can give scope for investigation from a very modern interdisciplinary approach

Download or read book Asymmetry written by Lisa Halliday and published by Simon and Schuster. This book was released on 2018-02-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A TIME and NEW YORK TIMES TOP 10 BOOK of the YEAR * New York Times Notable Book and Times Critic’s Top Book of 2018 NAMED ONE OF THE BEST BOOKS OF 2018 BY * Elle * Bustle * Kirkus Reviews * Lit Hub* NPR * O, The Oprah Magazine * Shelf Awareness The bestselling and critically acclaimed debut novel by Lisa Halliday, hailed as “extraordinary” by The New York Times, “a brilliant and complex examination of power dynamics in love and war” by The Wall Street Journal, and “a literary phenomenon” by The New Yorker. Told in three distinct and uniquely compelling sections, Asymmetry explores the imbalances that spark and sustain many of our most dramatic human relations: inequities in age, power, talent, wealth, fame, geography, and justice. The first section, “Folly,” tells the story of Alice, a young American editor, and her relationship with the famous and much older writer Ezra Blazer. A tender and exquisite account of an unexpected romance that takes place in New York during the early years of the Iraq War, “Folly” also suggests an aspiring novelist’s coming-of-age. By contrast, “Madness” is narrated by Amar, an Iraqi-American man who, on his way to visit his brother in Kurdistan, is detained by immigration officers and spends the last weekend of 2008 in a holding room in Heathrow. These two seemingly disparate stories gain resonance as their perspectives interact and overlap, with yet new implications for their relationship revealed in an unexpected coda. A stunning debut from a rising literary star, Asymmetry is “a transgressive roman a clef, a novel of ideas, and a politically engaged work of metafiction” (The New York Times Book Review), and a “masterpiece” in the original sense of the word” (The Atlantic). Lisa Halliday’s novel will captivate any reader with while also posing arresting questions about the very nature of fiction itself.

Download or read book The Psychology of Left and Right written by Michael C. Corballis and published by Routledge. This book was released on 2020-09-10 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1976, this title deals with the problem of how we tell left from right. The authors argue that the ability to tell left from right depends ultimately on a bodily asymmetry, such as preference for one or the other hand, or dominance of one side of the brain. This has implications for child development, reading disability, navigation, art, and culture.
Download or read book Foundations of Organic Chemistry written by David R. Dalton and published by John Wiley & Sons. This book was released on 2011-07-12 with total page 1440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book differs from other organic chemistry textbooks in that it is not focused purely on the needs of students studying premed, but rather for all students studying organic chemistry. It directs the reader to question present assumptions rather than to accept what is told, so the second chapter is largely devoted to spectroscopy (rather than finding it much later on as with most current organic chemistry textbooks). Additionally, after an introduction to spectroscopy, thermodynamics and kinetics, the presentation of structural information of compounds and organic families advances from hydrocarbons to alcohols to aldehydes and ketones and, finally, to carboxylic acids.

Download or read book Human Malformations and Related Anomalies written by Roger E. Stevenson and published by Oxford University Press. This book was released on 2005-10-27 with total page 1510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This widely acclaimed reference work gives a comprehensive survey of all significant human malformations and related anomalies from the perspective of the clinician. The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly. When known, the molecular or other pathogenetic basis for the malformation is given. Most anomalies are illustrated by photographs or drawings. Specific malformations are linked to syndromes through the extensive use of differential diagnosis tables. Over a decade has passed since the first edition of this book was published, and the revised edition fully incorporates the advances made in the field during the intervening years.. It reflects new understanding of human developmental biology that has emerged from molecular, cytogenetic, and biochemical studies; new observations by clinicians as well as enhanced diagnostic and prevention capacities; and more accurate and comprehensive epidemiology. By condensing much of the information presented in the first volume of the previous edition, and exercising rigorous editorial control, Drs. Stevenson and Hall and their contributors have managed to update the book while reducing its size to that of a single volume. All clinicians and scientists interested in birth defects, including pediatricians, geneticists, genetic counselors, obstetricians, and pediatric pathologists, will find this book to be an invaluable source of information.
