Peroxisomes are ubiquitous cell organelles that are particularly enriched in mammalian liver and kidney. They contain oxidases producing hydrogen peroxide and catalase, which degrades it. Their main functions are in the metabolism of complex lipids such as bile acids, leucotrienes and prostaglandins. Peroxisomes can be isolated by classical density gradient centrifugation methods and by more recent immunochemical techniques.
