Eight characteristics of the unique suite of amino acids and hydroxy acids found in the Murchison meteorite can be recognized on the basis of detailed molecular and isotopic analyses. The marked structural correspondence between the alpha-amino acids and alpha-hydroxy acids and the high deuterium/hydrogen ratio argue persuasively for their formation by aqueous phase Strecker reactions in the meteorite parent body from presolar, i.e., interstellar, aldehydes, ketones, ammonia, and hydrogen cyanide. The characteristics of the meteoritic suite of amino acids and hydroxy acids are briefly enumerated and discussed with regard to their consonance with this interstellar-parent body formation hypothesis. The hypothesis has interesting implications for the organic composition of both the primitive parent body and the presolar nebula.
基于详细的分子和同位素分析，可以识别出在默奇森陨石中发现的独特氨基酸和羟基酸组合的八个特征。α-氨基酸和α-羟基酸之间显著的结构对应关系以及高氘/氢比有力地证明了它们是由陨石母体中来自前太阳（即星际）醛、酮、氨和氰化氢通过水相施特雷克反应形成的。简要列举并讨论了陨石氨基酸和羟基酸组合的特征，以及它们与这种星际母体形成假说的一致性。该假说对原始母体和前太阳星云的有机组成具有有趣的启示。
