Abstract

The first results of the RAdiation Mechanism of Biomolecular ASymmetry (RAMBAS) experiment on investigation of the radiation mechanism of the influence on chiral molecules, as a factor leading to origination of chiral asymmetry are presented. It was found that irradiation of simple achiral materials by a flux of electrons from radioactive source initiated the synthesis of amino acids, and it resulted in asymmetric degradation and chiral asymmetry in a racemic mixture of amino acids. The results obtained can be important for the solution of the origin-of-life and biological homochirality problems.

摘要

本文介绍了生物分子不对称辐射机制（RAMBAS）实验的首批结果，该实验旨在研究辐射对手性分子的影响机制，而这种影响是导致手性不对称起源的一个因素。研究发现，来自放射源的电子束对简单的非手性物质进行辐照，引发了氨基酸的合成，并导致了氨基酸外消旋混合物的不对称降解和手性不对称。所获得的结果对于解决生命起源和生物同手性问题可能具有重要意义。
