Abstract

The treatment of isolated tea chloroplasts with potato lipolytic acyl hydrolase (LAHase) caused reduction of the activity for C6 aldehyde (1-hexanal, cis-3-hexenal, and trans-2-hexenal) formation from linoleic acid and linolenic acid. The activity of hydroperoxide cleavage enzyme was maintained even after potato LAHase treatment, whereas the activity for the overall reaction from C18 fatty acids to C6 aldehydes was decreased. These indicate that the activity of an oxygenation step, rather than a cleavage step, of C6 aldehyde formation was influenced by the treatment with potato LAHase.
