Amino Acids and the Asymmetry of Life: Caught in the Act of Formation"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. |

Indeed, when we produced a comet analogue in the laboratory, we found a wide variety of amino acid molecules and their mirror image forms therein. The results supported not only the concept of the extraterrestrial delivery of prebiotic ...

Westall for generous support in the laboratory and in language instruction. I explicitly thank Paul Vigny, former director of CBM, and Maryse Fauquembergue for the marvellous and complete organization of my French studies.
As a consequence, numerous examples of evolving structures and systems, which develop asymmetrically in timescales that can be observed in the laboratory, have been studied in great detail. However, despite a manifold of research ...
