Does the peroxisomes detoxify harmful substances in the body?

Peroxisomes' cell membrane have enzymes that do get rid of harmful, toxic materials within the cell. Additionally, peroxisomes help to break down fatty acid chains and alcohol. They are similar to lysosomes in ways, except the enzymes found in peroxisomes work in oxygen-rich areas, whereas lysosomes work in areas with less oxygen.

Interestingly, peroxisomes also produce toxic material--hydrogen peroxide. However, they are well-evolved enough to quickly breakdown the hydrogen peroxide into oxygen and water, which is harmless to the cell.
