| Research Abstract |
Recent studies suggest that there were oceans about 4 Gya and that the Earth might be subject to violent meteorite impacts (called LHB). Experimental study confirms the formation of biomolecules under such environments and prebiotic carbons in the sedimentary rocks have been found. Amino acid is a basic biomolecule for the origin of life and protein consists of L-amino acids. We investigated the chiral changes experimentally.The present experimental results on valine imply that impact effects on the chiral chemistry lead to an increase of D-enantiomer only in calcite and that L-enantiomer enrichment will occur little by impact.
