简介：
Overview
This article presents a simple, rapid, and cost-effective protocol for the large-scale enzymatic synthesis and purification of enantiopure epoxy fatty acids, specifically targeting arachidonic acid (AA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). The method utilizes a bacterial cytochrome P450 enzyme (BM3) to facilitate the preparation of these metabolites, which are historically challenging to obtain in pure form.
