Y-86029 and Y-980115 both show evidence of parent-body heating (500-600 °C) in addition to aqueous alteration, while Ivuna and Orgueil only show evidence for aqueous alteration. In contrast to Ivuna and Orgueil, which each contain 〜70 nmol/g of amino acids in acid-hydrolyzed, water extracts, both heated Yamato CI meteorites contain only low levels of amino acids that were primarily l-enantiomers of proteinogenic amino acids, indicating that they are likely to be terrestrial in origin. Because indigenous amino acids have been found in meteorites that have experienced metamorphic temperatures of >1000 °C with only minimal aqueous alteration, heating alone is not sufficient to explain the lack of amino acids in Y-86029 and Y-980115. Rather, our data suggest that the combination of heating and aqueous alteration has a profound destructive effect on amino acids in meteorites. This finding has implications for the origins of amino acids and other molecules in the early evolution of our solar system.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"コンドライト隕石に含まれるアミノ酸含有量および光学異性体の組成を、液体クロマトグラフィーおよび飛行時間型質量分析計により測定した。非南極コンドライトIvunaとOrgueilは水質変質の影響のみを受けているが、南極隕石、Yamato-86029および980115は水質変質作用と母天体加熱の影響を受けている。これらの南極隕石には、地球起源のアミノ酸しか確認できなかった。熱変成作用を受けた隕石にも、固有のアミノ酸が含まれていることから、加熱だけでは、アミノ酸が含まれていないことは説明できない。母天体での加熱と水質変質の両方が、隕石中のアミノ酸欠乏の原因になると考えられる。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009821640","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2014.05.002"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2014.05.002","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"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":"Burton, Aaron S."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Grunsfeld, Sarah"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Elsila, Jamie E."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Glavin, Daniel P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dworkin, Jason P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Burton, Aaron S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Grunsfeld, Sarah","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Elsila, Jamie E.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Glavin, Daniel P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dworkin, Jason P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Meteorite","subitem_subject_scheme":"Other"},{"subitem_subject":"Amino acid","subitem_subject_scheme":"Other"},{"subitem_subject":"CI chondrite","subitem_subject_scheme":"Other"},{"subitem_subject":"Aqueous alteration","subitem_subject_scheme":"Other"},{"subitem_subject":"Thermal metamorphism","subitem_subject_scheme":"Other"},{"subitem_subject":"Meteorite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Amino acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CI chondrite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Aqueous alteration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Thermal metamorphism","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The effects of parent-body hydrothermal heating on amino acid abundances in CI-like chondrites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The effects of parent-body hydrothermal heating on amino acid abundances in CI-like chondrites"},{"subitem_title":"The effects of parent-body hydrothermal heating on amino acid abundances in CI-like chondrites","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["1332"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-14"},"publish_date":"2014-10-14","publish_status":"0","recid":"10033","relation_version_is_last":true,"title":["The effects of parent-body hydrothermal heating on amino acid abundances in CI-like chondrites"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-07-25T16:22:15.863994+00:00"}
