Karen A O’Leary, Andrea J Day, Paul W Needs, Fred A Mellon, Nora M O’Brien and Gary Williamson, Biochemical Pharmacology, Volume 65, Issue 3, 1 February 2003, pages 479-491,〕 It is the sulfate conjugate of quercetin. Quercetin-3-sulfate 3'-sulfotransferase is an enzyme that uses 3'-phosphoadenylyl sulfate and quercetin 3-sulfate to produce adenosine 3',5'-bisphosphate and quercetin 3,3'-bissulfate. Quercetin-3-sulfate 4'-sulfotransferase is an enzyme that uses 3'-phosphoadenylyl sulfate and quercetin 3-sulfate to produce adenosine 3',5'-bisphosphate and quercetin 3,4'-bissulfate. Both enzymes can be found in ''Flaveria chlorifolia''. Quercetin-3,3'-bissulfate 7-sulfotransferase is an enzyme that uses 3'-phosphoadenylyl sulfate and quercetin 3,3'-bissulfate to produce adenosine 3',5'-bisphosphate and quercetin 3,7,3'-trissulfate. The enzyme can be found in ''Flaveria sp.'' == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quercetin 3-O-sulfate」の詳細全文を読む スポンサード リンク
