peroxisome

 [pĕ-roks´ĭ-sōm]
a microbody found in vertebrate animal cells, especially kidney and liver cells, that contains urate oxidase, amino acid oxidase, catalase, and other enzymes.

pe·rox·i·some

(pĕ-rok'si-sōm),
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.
[peroxide + G. sōma, body]

peroxisome

(pə-rŏk′sĭ-sōm′)
n.
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.

pe·rox·i·some

(pĕr-ok'si-sōm)
A membrane-bound organelle occurring in nearly all eukaryotic cells that often contains oxidative enzymes relating to the formation and degradation of H2O2.
Synonym(s): microbody.

peroxisome

an organelle of EUKARYOTE cells which is surrounded by a single unit membrane. Peroxisomes contain PEROXIDASES and may be concerned with the production of molecular oxygen from the breakdown of hydrogen peroxide. They are located near MITOCHONDRIA and plant CHLOROPLASTS, and appear to be involved in CELLULAR RESPIRATION.
