25(S) THCA-CoA and O2 react to form 3alpha,7alpha,12alpha-trihydroxy-5beta-cholest-24-enoyl-CoA (THCA-CoA) and H2O2. This dehydrogenation reaction occurs in the peroxisomal matrix. It is catalyzed by the FAD-containing peroxisomal enzyme branched chain acyl-CoA oxidase (ACOX2). The enzyme transfers electrons to molecular oxygen and hydrogen peroxide is produced as a byproduct.
