Abstract

Isoprostanes are products of free radical-catalyzed oxidation of arachidonic acid (20:4) in mammals [1], However, isoprostanoids can be formed virtually from any natural polyunsaturated fatty acid that contains at least three double bonds. a-Linolenic acid (18:3) fulfills that criterion, and thus, can be oxidized to a variety of C-18 isoprostane classes (dinor isoprostanes) [2]. Dinor isoprostanes in animals are either derived from β- oxidation of C20 isoprostanes or peroxidation of γ-linolenic acid (18:3) but not from α-linolenic acid which is only a trace fatty acid in mammals [3,4]. In contrast, higher plants generally are devoid of arachidonate and biosynthesize α-linolenate as one of the major polyunsaturated fatty acids. Since α-linolenate derived dinor isoprostanes differ in structure from mammalian dinor isoprostanes, plant dinor isoprostanes have been termed phytoprostanes [5].
