Functions of peroxisome^a

1.	Respiration: H2O2-producing oxidases, catalase
2.	Fatty acid β-oxidation: acyl-CoA oxidase, bifunctional protein (hydratase-dehydrogenase), thiolase
3.	Ether glycerolipid (plasmalogen) biosynthesis: DHAP-ATPase, alkyl-DHAP synthase
4.	Transamination and oxidation (gluconeogenesis): serine-pyruvate aminotransferase (alanine-glyoxylate aminotransferase)
5.	Purine catabolism
6.	Polyamine catabolism
7.	Bile acid biosynthesis
8.	Pipecolic acid catabolism
9.	Phytanic acid catabolism

^aRepresentative functions in mammalian peroxisomes are listed, where peroxisomal enzymes involved in the functions (1 to 4) are also described.
