It is the precursor to one of the three principal lignols. ==Preparation and occurrence== In the laboratory, caffeyl alcohol can be synthesized from 1,2-dihydroxy-4-benzaldehyde.〔Karl Herrmann “Caffeyl Alcohol” Pharmazie 1953, volume 8, 303.〕 It is an intermediate in the biosynthesis of coniferyl alcohol, the conversion being effected by caffeate O-methyltransferase.〔John M Humphreys, Clint Chapple “Rewriting the Lignin Roadmap” Current Opinion in Plant Biology 2002, volume 5, 224–229. 〕 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「Caffeyl alcohol」の詳細全文を読む スポンサード リンク
