标题： The start of the Abiogenesis: Preservation of homochirality in proteins as a necessary and sufficient condition for the establishment of the metabolism

摘要： 生物系统包含几乎无限多的重要细节，这些细节共同确保了它们的生命。 然而，这些系统中有一些共同的结构和反应：碳水化合物和蛋白质的同手性，代谢和遗传学。 生命起源，即自生过程，可能不是一系列单一事件的结果，而是分子和化学反应复杂性逐渐增加的渐进过程的结果，而生命前分子的合成可能没有留下进化初期结构和反应建立的痕迹。 但另一方面，人们或许能够确定生命起源过程中化学因子形成的顺序。 在这里，我们回顾实验结果，并提出一个生命起源开始的模型，在该模型中，蛋白质的同手性自发形成是碳水化合物同手性和生命起源初期代谢建立的前提条件。 显示英文摘要

摘要： Biosystems contain an almost infinite amount of vital important details, which together ensure their life. There are, however, some common structures and reactions in the systems: the homochirality of carbohydrates and proteins, the metabolism and the genetics. The Abiogenesis, or the origin of life, is probably not a result of a series of single events, but rather the result of a gradual process with increasing complexity of molecules and chemical reactions, and the prebiotic synthesis of molecules might not have left a trace of the establishment of structures and reactions at the beginning of the evolution. But alternatively, one might be able to determine some order in the formation of the chemical denominators in the Abiogenesis. Here we review experimental results and present a model of the start of the Abionenesis, where the spontaneous formation of homochirality in proteins is the precondition for the establishment of homochirality of carbohydrates and for the metabolism at the start of the Abiogenesis.
