Based on the results on electrochemical decomposition of amino acids in CO2-saturated solution, I have studied the amino acid decomposition chemistry on the parent bodies of carbonaceous chondrites and asteroid. The significance is that these extraterrestrial samples could have provided amino acids for seeding origin of life on Earth. These research results have resulted in one publishedpaper (Nature Communications, 2022) and one manuscript currently under review (Li et al., under review). Our major finding is that aqueous alteration can lead to complex behavior of organics on its parent body, including both synthetic and breakdown mechanisms. Our findings suggest that water/rock differentiated Solar System bodies could have generated the chemical heterogenity in various samples.

基于氨基酸在CO_2饱和溶液中的电化学分解研究结果，本文研究了氨基酸在碳质陨石和小行星母体上的分解化学。重要的是，这些外星样本可能为地球上生命的起源提供了氨基酸。这些研究结果已经产生了一篇论文（Nature Communications，2022）和一篇正在审查的手稿（Li等人，审查中）。我们的主要发现是，水蚀变可以导致其母体上的有机物的复杂行为，包括合成和分解机制。我们的研究结果表明，水/岩石差异化的太阳系天体可能在各种样本中产生了化学不均匀性。
