Outline of Final Research Achievements

Purpose of this study is to clarify the process of homochiral worlds expressed in our biosphere from a slight asymmetrical compounds that are believed to have expressed in a space environment. We added a chiral amino acid without racemization during the experiment is added into the prebiotic polyamino acids (proteinoids) producing systems. Then, the chirality of the products would be analyzed.
Molten state experiment of monoammonium malate was used the proteinoid formation. Racemic alanine and chiral isovaline were added into the reaction. LC-MS analysis of the products indicated the possibility that optically active proteinoids were produced.
