Abstract The analysis of the organic matter meteorites made it possible to identify over 70 amino acids (AA), including 8 those found in living organisms. However, their relative abundances vary drastically with type carbonaceous chondrite, even for isomers same chemical formula. In this report we address question whether difference may have its origin stability these according conditions they ...

Introduction: There is an established relationship between organic matter content and aqueous alteration processes [1,2]. However, the relationship between meteoritic organic matter and individual aqueously generated mineral matrix phases is poorly understood. Meteoritic organic matter is primarily composed of C, H and N and therefore their bulk abundances in chondrites are strongly controlled ...
