Medical Term:

peroxisome

Pronunciation: pe-rok'si-som

Definition: A membrane-bound organelle occurring in many eukaryotic cells that often has an electron-dense crystalline inclusion containing catalase, urate oxidase, and other oxidative enzymes relating to the formation and degradation of H2O2; thought to be important in detoxifying various molecules and in catalyzing the breakdown of fatty acids to acetyl-CoA; an absence of peroxisomes is found in patients with Zellweger syndrome.
