AI overview
A peroxisome is a small, membrane-bound compartment inside cells that contains enzymes and helps break down fatty acids and other molecules. These organelles are important for protecting cells from harmful substances called peroxides, which they break down into water and oxygen.

A peroxisome () is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells. Peroxisomes are oxidative organelles. Frequently, molecular oxygen serves as a co-substrate, from which hydrogen peroxide (H2O2) is then formed. Peroxisomes owe their name to hydrogen peroxide-generating and scavenging activities. They perform key roles in lipid metabolism and the reduction of reactive oxygen species.
