Non-Enzymatic Isomerization of 12-Hydroxy-(3Z)-dodecenal to the (2JE)-Isomer after Enzymatic Cleavage of 13-HydroperoxylinoIeyl Alcohol in Tea Chloroplasts
نویسندگان
چکیده
Incubation of synthetic 12-hydroxy-(3Z)-dodecenal (3ZHD) with tea chloroplasts revealed that 12-hydroxy-(2£)-dodecenal (2EHD) was the product of isomerization reaction of 3ZHD during the incubation. The isomerization was caused also by incubation of 3ZHD with the heat-inactivated chloroplasts. The isomerization activity was extracted with hot ethanol. These results indicate that the isomerization was caused by heat-stable factor(s) but not by enzyme(s) in tea chloroplasts.
