Abstract: | 9-Hydroxy-traumatin, 9-hydroxy-12-oxo-10E-dodecenoic acid, was isolated as a product of 13S-hydroperoxy-9Z, 11E-octadecadienoic acid as catalyzed by enzyme preparations of both soybean and alfalfa seedlings. This suggested that 9Z-traumatin, 12-oxo-9Z-dodecenoic acid, was being converted into 9-hydroxy-traumatin in an analogous manner to the previously identified enzymic
conversion of 3Z-nonenal and 3Z-hexenal into 4-hydroxy-2E-nonenal and 4-hydroxy-2E-hexenal, respectively. Other metabolites of 13S-hydroperoxy-9Z,11E-octadecadienoic acid were similar for both soybean and alfalfa seedling preparations, and they are briefly described. |
