Abstract

A new chromogen that absorbs maximally at 329 nm was frequently found in the liver oils of the freshwater fish Bagarius bagarius and Wallago attu. It was shown to be a diester of 3-hydroxyretinol. 3-Hydroxyretinol was found to be a metabolite of lutein during the biosynthesis of 3-dehydroretinol in a freshwater fish. A new method for the chemical synthesis of 3-hydroxyretinol from methyl 3-dehydroretinoate is described. The possible pathway for the conversion of lutein into 3-dehydroretinol in vivo is discussed.

摘要

在淡水鱼巨魾和孔鳢的肝油中经常发现一种在329纳米处有最大吸收的新型色原。结果表明它是3-羟基视黄醇的二酯。在淡水鱼3-脱氢视黄醇的生物合成过程中,3-羟基视黄醇被发现是叶黄素的一种代谢产物。本文描述了一种从3-脱氢视黄酸甲酯化学合成3-羟基视黄醇的新方法。文中还讨论了叶黄素在体内转化为3-脱氢视黄醇的可能途径。
