Peroxisomes are found in all eukaryotic cells. Peroxisomes contain enzymes for certain oxidative reactions. Prokaryotes lack peroxisomes, so they are more vulnerable to toxic substances like hydrogen peroxide. Full article >>>
Peroxisomes are ubiquitous organelles in eukaryotes. They consist of a single membrane that separates them from the cytosol (the internal fluid of the cell). Peroxisomes were discovered by Christian de Duve in 1965. Full article >>>
Peroxisome Disorders A variety of rare inherited disorders of peroxisome function occur in humans. Most involve mutant versions of one or another of the enzymes found within peroxisomes. Full article >>>
Peroxisomes are vesicles that contain enzymes which oxidize (remove hydrogen) from a variety of different compounds and pass the hydrogen to oxygen. During these reactions, hydrogen peroxide (H2O2) is formed. Full article >>>
peroxisome (per-oks-eh-some) A microbody containing enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide. Full article >>>
peroxisomes Membrane-bound vesicles in eukaryotic cells that contain oxidative enzymes. pesticides Chemicals that are applied to agricultural crops or domesticated plants and which kill or inhibit growth of insects. Full article >>>
peroxisome Membrane-bounded organelle in the cytoplasm of eukaryotic cells functioning in the destruction of proteins and characterized by peroxide-forming enzymes. pH The negative logarithm of the hydrogen ion concentration in an aqueous solution. Full article >>>
