作用与用途

Analysis Note Protein determined by biuret.
Application The soybean enzyme will use arachidonic acid as a substrate, with ~ 15% of the activity indicated using linoleic acid as the substrate; the product of arachidonic acid oxidation is 12- or 15-hydroperoxyarachidonic acid (12-HPETE or 15-HPETE).

Biochem/physiol Actions Catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure.
Unit Definition One unit will cause an increase in A234 of 0.001 per min at pH 9.0 at 25 °C when linoleic acid is the substrate in 3.0 ml volume (1 cm light path). One A234 unit is equivalent to the oxidation of 0.12 μmole of linoleic acid.
Physical form Contains stabilizer and NaCl
