The recent paper by Belo, Pereira, Freire, Argyriou, Eckert & Bordallo [(2018 ▸), , , 6-12] reports observations that may lead one to think of very strong and visible consequences of the parity-violation energy difference between enantiomers of a molecule, namely alanine. If proved, this claim would have an enormous impact for research in structural chemistry. However, alternative, more realistic, explanations of their experiments have not been ruled out by the authors. Moreover, the theoretical calculations carried out to support the hypothesis are unable to differentiate between enantiomers (molecules or crystals). Therefore, the conclusions drawn by Belo (2018 ▸) are deemed inappropriate as the data presented do not contain sufficient information to reach such a conclusion.
贝洛、佩雷拉、弗雷雷、阿吉里奥、埃克特和博尔达洛最近发表的论文[（2018▸），，，6 - 12]报告了一些观察结果，这些结果可能会让人想到分子对映体（即丙氨酸）之间宇称破缺能量差所产生的非常强烈且明显的后果。如果这一说法得到证实，将对结构化学研究产生巨大影响。然而，作者并未排除对他们实验的其他更现实的解释。此外，为支持该假设所进行的理论计算无法区分对映体（分子或晶体）。因此，贝洛（2018▸）得出的结论被认为是不合适的，因为所呈现的数据并不包含足以得出该结论的充分信息。
