Reaction: 25(S) DHCA-CoA is dehydrogenated to 25(S) 3alpha,7alpha-dihydroxy-5beta-cholest-24-enoyl-CoA

- in pathway: Synthesis of bile acids and bile salts via 7alpha-hydroxycholesterol
25(S) DHCA-CoA and O2 react to form 25(S) 3alpha,7alpha-dihydroxy-5beta-cholest-24-enoyl-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.
