We can point out two interesting and important properties on amino acids in terrestrial lives: first is that only approximately 20 kinds of amino acids are utilized in proteinic materials of terrestrial lives. Second is that the relative molar ratios between 20 amino acids are almost equal. In our present paper, paying attention to these facts, we make an attempt to specify physical and chemical properties of a primordial Earth environment. By assuming that two amino acids and appropriate inorganic elements are in chemical equilibrium, we can find the activity ratios (or activities) of inorganic elements under the condition of typical hydrothermal fluid. Our results suggest that the hydrothermal fluid environment must be in a reducing condition and the oxidizing elements like O2 or SO2 cannot contribute the equilibrium reactions.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350013","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京工業大学 理学部　地球惑星科学科"},{"subitem_text_value":"東京工業大学 理学部　地球惑星科学科"},{"subitem_text_value":"東京工業大学 理学部　地球惑星科学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology Department of Earth and Planetary Sciences, School of Science"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology Department of Earth and Planetary Sciences, School of Science"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology Department of Earth and Planetary Sciences, School of Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山口, 善光"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中澤, 清"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"榎森, 啓元"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Yoshimitsu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakazawa, Kiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Emori, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"惑星進化","subitem_subject_scheme":"Other"},{"subitem_subject":"地表面","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星表面","subitem_subject_scheme":"Other"},{"subitem_subject":"化学平衡","subitem_subject_scheme":"Other"},{"subitem_subject":"蛋白質","subitem_subject_scheme":"Other"},{"subitem_subject":"アミノ酸","subitem_subject_scheme":"Other"},{"subitem_subject":"化学反応","subitem_subject_scheme":"Other"},{"subitem_subject":"化学量論","subitem_subject_scheme":"Other"},{"subitem_subject":"有機化合物","subitem_subject_scheme":"Other"},{"subitem_subject":"水熱系","subitem_subject_scheme":"Other"},{"subitem_subject":"水熱流体","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary evolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Earth surface","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary surface","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"chemical equilibrium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"protein","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"amino acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"chemical reaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stoichiometry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"organic compound","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrothermal system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrothermal fluid","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Primordial Earth's environment suggested from equilibrium conditions among amino acids","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Primordial Earth's environment suggested from equilibrium conditions among amino acids","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1791","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20528","relation_version_is_last":true,"title":["Primordial Earth's environment suggested from equilibrium conditions among amino acids"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:49:00.916500+00:00"}
