Peroksisomikalvoon

Peroksisomikalvoon refers to the membrane that encloses a peroxisome. Peroxisomes are small, membrane-bound organelles found in the cells of eukaryotes, including animals, plants, fungi, and protozoa. They play a crucial role in various metabolic processes, notably in detoxifying harmful substances and breaking down fatty acids. The membrane of the peroxisome is a single lipid bilayer, similar in structure to other cellular membranes such as the plasma membrane and the endoplasmic reticulum. This membrane is selectively permeable, regulating the passage of molecules into and out of the peroxisome. It contains specific transport proteins that facilitate the import of enzymes and other proteins synthesized in the cytoplasm and the export of metabolic products. The peroxisomal membrane is also involved in the replication of peroxisomes, a process that occurs through growth and division. Unlike some other organelles, peroxisomes do not possess their own genetic material; their proteins are encoded by nuclear genes and imported from the cytosol. The integrity of the peroksisomikalvoon is essential for the proper functioning of the peroxisome and for maintaining cellular homeostasis. Defects in peroxisomal membrane proteins or their assembly can lead to a class of genetic disorders known as peroxisome biogenesis disorders.
