Peroksisoma (peroxysoma) — it is small (the size 0,3 — 1,5 microns) an oval form of a little body, limited to a membrane, containing granular матрикс in which center the kristallopodobny structures consisting of fibrilla and tubes (core) are often visible. Peroksisoma probably are formed on the expanded parties of tanks of an endoplasmic network. They are especially characteristic for cells of a liver and kidneys. In fraction peroksisy enzymes of oxidation of amino acids during which work hydrogen peroxide is formed are found, and also enzyme the catalase destroying it comes to light. The catalase the peroksisy plays an important protective role as H2O2 is toxic substance for the cage.
Thus, EPS, Golgi's complex, lysosomes, peroksisoma – the membrane organellas of a cage making vakuolyarny system provide synthesis and transport of intracellular biopolymers, the products of secretion brought out of a cage that is followed by biosynthesis of all membranes of this vakuolyarny system. Derivatives of vakuolyarny system — a lysosome and a peroksioma — participate in degradation of exogenous and endogenous substrata of a cage.
