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.
