A cell organelle containing a large number of enzymes, including catalase and oxidase, that break down long-chain fatty acids and other organic molecules. The hydrogen peroxide produced by these reactions is also broken down within the peroxisome.

per·ox′i·som′al (-sō′məl) adj.


(Biochemistry) biology a type of organelle present in most eukaryotic cells that carry out oxidative reactions, such as oxidation of alcohol in the liver
