openfree Perxoisome

peroxisome (IPA: [pɛɜˈɹɒksɪˌsoʊm])[1] is a type of organelle known as a microbody, found in virtually all eukaryotic cells.[2] They are involved in catabolism of very long chain fatty acidsbranched chain fatty acidsD-amino acids, and polyaminesreduction of reactive oxygen species – specifically hydrogen peroxide[3] – and biosynthesis of plasmalogens, i.e., ether phospholipids critical for the normal function of mammalian brains and lungs.[4] They also contain approximately 10% of the total activity of two enzymes in the pentose phosphate pathway, which is important for energy metabolism.[4] It is vigorously debated whether peroxisomes are involved in isoprenoid and cholesterol synthesis in animals.[4] Other known peroxisomal functions include the glyoxylate cycle in germinating seeds ("glyoxysomes"), photorespiration in leaves,[5] glycolysis in trypanosomes ("glycosomes"), and methanol and/or amine oxidation and assimilation in some yeasts.
