• Amino acids in terrestrial living organisms are exclusively of one enantiomer, L-form. Again surprisingly the same handedness of enantiomeric excesses (EEs) of amino acids in several meteorites (e.g., Murchison, Murray, Orgueil) has been found. These enantiomeric excesses which refers to the phenomenon of origin of homochirality may be caused by circularly polarizes UV radiation. It is considered that asymmetric synthesis and decomposition of organic compounds were imported on the early earth by meteorite and circularly polarized radiation has been observed around the massive star forming region in where our solar system was formed. In this study, we examined asymmetric decomposition and chirality formation of amino acids by circularly polarized UV irradiation. We used histidine, isovaline and 5-ethyl-5-methylhydantoin solutions. We also performed UV irradiation (D_2 lamp) of amino acids and 5-Ethyl-5-methylhydantoin to contrast the irradiated products.
