Peroxisomes are small, membrane-bound organelles found in the cytoplasm of eukaryotic cells. They are involved in various metabolic processes, including the breakdown of very long-chain fatty acids, the synthesis of plasmalogens, and the detoxification of hydrogen peroxide. Peroxisomes are particularly abundant in cells that require high levels of fatty acid oxidation, such as liver, kidney, and heart cells.

The term "peroxisome" was coined by Christian de Duve in 1967, who discovered these organelles in rat liver cells. Peroxisomes are characterized by their single membrane and the presence of specific enzymes, such as catalase and urate oxidase, which are involved in the breakdown of hydrogen peroxide and other reactive oxygen species.

Peroxisomes play a crucial role in maintaining cellular homeostasis by regulating the levels of reactive oxygen species. They also contribute to the synthesis of essential biomolecules, such as plasmalogens, which are important components of cell membranes. Additionally, peroxisomes are involved in the metabolism of amino acids and the synthesis of bile acids in the liver.

The structure and function of peroxisomes can be altered by various factors, including genetic mutations, environmental toxins, and age-related changes. Dysfunction of peroxisomes has been linked to several human diseases, such as Zellweger syndrome, Refsum disease, and X-linked adrenoleukodystrophy. Understanding the biology of peroxisomes is therefore important for the study of normal cellular function and the development of therapeutic strategies for peroxisomal disorders.
