Peroksisoominagu

Peroksisoominagu refers to the microscopic structures within eukaryotic cells known as peroxisomes. These membrane-bound organelles play a crucial role in various metabolic processes. Their primary function involves the breakdown of fatty acids, a process that generates hydrogen peroxide as a byproduct. Peroxisomes contain enzymes, notably catalase, which then detoxify this hydrogen peroxide, converting it into water and oxygen, thus preventing cellular damage.

Beyond fatty acid metabolism, peroxisomes are involved in the synthesis of certain lipids, including plasmalogens, which are important components of cell membranes, particularly in the nervous system. They also participate in the detoxification of various toxic compounds, such as alcohol, and are involved in the metabolism of amino acids and purines. The number and size of peroxisomes can vary depending on the cell type and its metabolic needs. Their formation is thought to arise from the endoplasmic reticulum. Defects in peroxisome function are associated with several genetic disorders, highlighting their essential role in cellular health and organismal well-being.
