However, the detailed reaction mechanism has yet to be fully clarified.  In this study, the kinetic isotope effect was investigated for the reaction of Trolox, a water soluble vitamin E analog, with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical solubilized by beta-cyclodextrin in water.  A deuterium kinetic isotope effect of 5.0 was observed in 0.1 M BIS-TRIS buffer (pH/pD 6.9).  The DPPH radical-scavenging mechanism of Trolox will be discussed on the basis of the effect of pH and solvents on the second-order rate constants observed in this study.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"日本化学会第99春季年会","subitem_description_type":"Other"}]},"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":"Nakanishi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"734945","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohkubo, Kei"}],"nameIdentifiers":[{"nameIdentifier":"734946","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, Toshihiko"}],"nameIdentifiers":[{"nameIdentifier":"734947","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken-ichiro, Matsumoto"}],"nameIdentifiers":[{"nameIdentifier":"734948","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Ikuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"734949","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohkubo, Kei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"734950","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, Toshihiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"734951","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Kenichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"734952","nameIdentifierScheme":"WEKO"}]}]},"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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Kinetic Isotope Effect in the Scavenging Reaction of a Water-Solubilized Organic Radical by a Vitamin E Analog","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Kinetic Isotope Effect in the Scavenging Reaction of a Water-Solubilized Organic Radical by a Vitamin E Analog"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-15"},"publish_date":"2019-01-15","publish_status":"0","recid":"74846","relation_version_is_last":true,"title":["Kinetic Isotope Effect in the Scavenging Reaction of a Water-Solubilized Organic Radical by a Vitamin E Analog"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T07:54:11.133178+00:00"}
