Book Description
"How did life originate and why were left-handed molecules selected for its architecture?" This question of high public and interdisciplinary scientific interest is the central theme of this book. It is widely known that in processes triggering the origin of life on Earth, the equal occurrence, the parity between left-handed amino acids and their right-handed mirror images, was violated. The balance was inevitably tipped to the left – as a result of which life's proteins today exclusively implement the left form of amino acids. Written in an engaging style, this book describes how the basic building blocks of life, the amino acids, formed. After a comprehensible introduction to stereochemistry, the author addresses the inherent property of amino acids in living organisms, namely the preference for left-handedness. What was the cause for the violation of parity of amino acids in the emergence of life on Earth? All the fascinating models proposed by physicists, chemists and biologist are vividly presented including the scientific conflicts. The author describes the attempt to verify any of those models with the chirality module of the ROSETTA mission, a probe built and launched with the mission to land on a comet and analyse whether there are chiral organic compounds that could have been brought to the Earth by cometary impacts. A truly interdisciplinary astrobiology book, "Amino Acids and the Asymmetry of Life" will fascinate students, researchers and all readers with backgrounds in natural sciences. With a foreword by Henri B. Kagan.

Book Description
Astrobiology is an expanding, interdisciplinary field investigating the origin, evolution and future of life in the universe. Tackling many of the foundational debates of the subject, from discussions of cosmological evolution to detailed reviews of common concepts such as the 'Rare Earth' hypothesis, this volume is the first systematic survey of the philosophical aspects and conundrums in the study of cosmic life. The author's exploration of the increasing number of cross-over problems highlights the relationship between astrobiology and cosmology and presents some of the challenges of multidisciplinary study. Modern physical theories dealing with the multiverse add a further dimension to the debate. With a selection of beautifully presented illustrations and a strong emphasis on constructing a unified methodology across disciplines, this book will appeal to graduate students and specialists who seek to rectify the fragmented nature of current astrobiological endeavour, as well as curious astrophysicists, biologists and SETI enthusiasts.

Book Description
Biological Chirality describes this occurrence, its history, and early research around the topic. The work covers analytical methods for observing the phenomenon, providing current techniques and practice and discussing the asymmetric morphology of certain living organisms, such as the position of the heart and liver in humans and the exceptions to biological homochirality seen in D-Amino Acids. In addition, it explores the requirement of enantioselectivity prepared pharmaceuticals to address enantioselectivities biomolecules, a major challenge in today's organic chemistry. Finally, the work considers the possible origin of biological homochirality, as well as the outlook for future research in this area. - Describes the history of biological chirality research, its possible origins, and future exploration areas - Discusses asymmetric exceptions in morphology and D-Amino Acids - Explores the critical implications of enantioselective biomolecules for preparative organic chemistry with a goal of developing effective pharmaceuticals

Book Description
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.

Book Description
McManus considers evidence from anthropology, particle physics, the history of medicine, and the notebooks of Leonardo to answer questions like: Why are most people right-handed? Why does European writing go from left to right, while Arabic and Hebrew go from right to left? And how do we know that Jack the Ripper was left-handed?
