Coupled oxidation of carotene and linoleate catalyzed by lipoxidase.

The coupled oxidation of carotenoids and certain unsaturated fatty acids by lipoxidase has long been of interest. It not only has economic importance because of destruction of a valuable feed constituent, carotene, but is an apparently unique enzymatic reaction, regarded by some as an example of a free radical chain reaction in a polyphase system (1). Although considerable work has been done on...

The reaction mechanism of soy bean lipoxidase.

Based on their observations that the lipoxidase-catalyzed oxidation of linoleate, like autoxidation, gave primarily conjugated diene peroxides (1,2) and caused a coupled oxidation of some easily oxidizable substances, such as carotenoids (3) and antioxidants (4), Bergstrom and Holman proposed a reaction mechanism for lipoxidase catalysis. They suggested (4) that lipoxidase could cause initiatio...

Inhibition by Antioxidants of Alfalfa Enzyme Catalysis Inhibition of the Antioxidant Concentration Initial Reaction

The presence of the enzyme lipoxidase in alfalfa has been reported (3, 5, 6). However, the properties of this postulated alfalfa lipoxidase are quite different from the well known properties of soybean lipoxidase. Strain (5) showed that the alfalfa enzyme acts on oleic and ricinoleic acids, however it is known that soybean lipoxidase acts only on linoleic, linolenic and arachidonic acids. -Mitc...

Chemotropic Response of the Pollen of Antirrhinum majus to Calcium.

An improved spectrophotometric method for the determination of lipoxidase activity was developed and applied in studies of the purified enzyme and crude enzyme preparations from leguminous seeds, with linoleic acid solubilized in Tween 20 as the substrate. The optimum pH was found to be 7.0, 6.5, 6.0, and 5.5, for purified soybean lipoxidase and for the crude lipoxidases extracted from gram flo...

Induction period in the lipoxidase-catalyzed oxidation of linoleic acid and its abolition by substrate peroxide.

The non-enzymatic oxidation of linoleate occurs with a definite induction period. Bolland has explained the kinetics of the oxidation in terms of a chain reaction involving free radicals (1). The discovery by Privett et al. (2) that the peroxide formed by the action of lipoxidase is optically active clearly rules out the possibility of a non-enzymatic chain sequence, but it is not impossible th...
