title: [Investigations on the development of volatile substances during lipoxygenase-linolic-acid-reaction (author's transl)].
abstract: During incubation of soja-lipoxygenase with linolic acid, volatile compounds are formed the development of which can be seen in two possible ways:from preformed linolic-acid-hydroperoxides splitproducts arise or volatile substances of different chemical nature are built depending on the reaction conditions like temperature, O2-pressue, partner-concentration etc. By trials with hydroperoxyde-decomposing enzymes (peroxidase) and by means of radio-active labelled linolic-acid-hydroperoxides the pathways mentioned above were investigated. The results indicate that the volatile compounds are built from by-products; n-hexanal was formed from these by-products as well as from decomposed hydroperoxide. The previously proposed reaction-scheme has this been ascertained by experimental means.
