Formation of 4-hydroxy-2-alkenals in barley leaves

Biochem Soc Trans. 2000 Dec;28(6):850-1.

Abstract

In barley leaves 13-lipoxygenases are induced by jasmonates. This leads to induction of lipid peroxidation. Here we show by in vitro studies that these processes may further lead to autoxidative formation of (2E)-4-hydroxy-2-hexenal from (3Z)-hexenal.
