The major function of peroxisomes is:
Peroxisomes are single membrane oxidative organelles discovered by Rhodin and De Duve, numbering hundreds per cell, containing more than fifty enzymes producing and degrading hydrogen peroxide. Beta-oxidation of very long chain fatty acids greater than twenty two carbons, branched phytanic acid alpha-oxidation, bile acid intermediate shortening and ether lipid synthesis of plasmalogens providing antioxidant membranes and myelin components occur via enzymes acyl-CoA oxidase generating H2O2, bifunctional enzyme and thiolase. Catalase converts two H2O2 to water and oxygen detoxifying, also urate
