Do peroxisomes break down fatty acids or alcohol

Yes, peroxisomes are key sites for the breakdown of very-long-chain and branched-chain fatty acids through beta-oxidation. This process shortens fatty acids to forms usable by mitochondria for further energy production. Additionally, peroxisomes metabolize certain alcohols such as ethanol by oxidizing them through specific oxidases, producing hydrogen peroxide, which is then detoxified. These catabolic activities are essential for preventing toxic accumulation of fatty acids and alcohol metabolites in the cell.
