Aerobic pentane production by soybean lipoxygenase isozymes

The effects of oxygen on production of pentane and compounds absorbing at 234 nm and 285 nm by soybean lipoxygenase isozymes I and II were examined in a model system. Aerobic conditions increased pentane production. Differences in dienone formation (A285) and diene conjugation (A234) indicate the reaction sequences of the 2 isozymes are not the same.
