These enzymes are abundant in the animal homologues of (*) glyoxysomes.
One of these enzymes performs the first step in the synthesis of leukotrienes from arachidonic acid. One subset of these proteins produces glutathione disulfide and protects membrane lipids against a free-radical chain that may terminate in malonaldehyde. These enzymes are abundant in the animal homologues of (*) glyoxysomes. In those organelles, carnitine acyltransferase initiates beta-oxidation, producing a substrate for these enzymes as a reduced byproduct. During a respiratory burst, one of these enzymes generates hypochlorite in azurophilic granules in neutrophils. The most common enzyme of this type is used in a test to identify Streptococcus; that enzyme is catalase. For 10 points, name this class of enzymes that split R-O-O-R groups.
