Abstract: Compound-specific carbon isotope analysis (d13C) of meteoritic organic compounds can be used to elucidate the abiotic chemical reactions involved in their synthesis. The soluble organic content of the Murchison carbonaceous chondrite has been extensively investigated over the years, with a focus on the origins of amino acids and the potential role of Strecker-cyanohydrin synthesis in the early solar system. Previous d13C investigations have targeted a-amino acid and a-hydroxy acid Strecker pr...
