Enantioselectivity of enzymatic cleavage reaction of 13-hydroperoxylinolenic acid to C6-aldehyde and C12-oxo acid in tea chloroplasts.

Abstract

Wehave demonstrated that C6-aldehydes ((3Z)-hexenal and -hexanal) were produced from LNAor LA by the enzymes bound to chloroplast lamellae of tea leaves.1 ~6) In a previous paper, two enzymes (E2\ lipoxygenase and E2 \ hydroperoxide lyase)4'7~10) were reported to be involved in the C6-aldehyde forming enzyme system in isolated tea chloroplasts;
