The phenomenon is different from chiral amplification, where enantiomeric excess is present from the beginning and not stochastically distributed. Hence, when the experiment is repeated many times, the average enantiomeric excess approaches 0%.〔Kenta Suzuki, Kunihiko Hatase, Daisuke Nishiyama, Tsuneomi Kawasaki, Kenso Soai, ''Journal of Systems Chemistry'' 2010, 1:5 (18 August 2010), 〕 The phenomenon has important implications concerning the origin of homochirality in nature. == References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spontaneous absolute asymmetric synthesis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
