Research Abstract

本研究は、脂質修飾糖加水分解酵素を用いて炭酸超臨界流体中での位置選択的グリコシド転移反応を行うことを目的として行い、以下の成果を得た。
圧力と温度を変えることにより超臨界流体の密度と極性が自由に制御できるので、種々の反応条件下で酵素反応速度を検討した。またイソオクタンなどの有機溶媒中との反応速度や収率とも比較した。
受容体としてのアルコール分子(R-OH)を変えて様々な有用配糖化合物を合成した。
リパーゼによるエステル合成反応、さらには二酸化炭素自体を基質として、ビルピン酸カルボキシラーゼにより二酸化炭素を有機物に転換するいわゆる"炭酸固定"反応についても検討した。
