peroxisome
Fatty acid processor
A peroxisome is a small structure within cells that breaks down fatty acids and neutralizes toxic substances, particularly hydrogen peroxide—hence the name.
Found in nearly all eukaryotic cells, peroxisomes are especially abundant in liver and kidney cells, where detoxification demands are high.
