Biosynthesis of Leaf Alcohol Formation of 3Z-Hexenal from Linolenic Acid in Chloroplasts of Thea Sinensis Leaves

Abstract

The synthetic activity for 3Z-hexenal, an important precursor of 3Z-hexenol (leaf alcohol), was localized in chloroplasts of Thea sinensis leaves. 3Z-Hexenal, which is easily isomerized to 2E-hexenal (leaf aldehyde), was formed from linolenic acid in the presence of oxygen. 13-L-Hydroperoxy-linolenic acid also served as a precursor, but the triglyceride and methyl ester of linolenic acid did not. This enzyme system appeared to be tightly bound to the lamellae membranes of chloroplasts. © 1976, Japan Society for Bioscience, Biotechnology, and Agrochemistry. All rights reserved.
