Peroxisome, membrane-bound organelle occurring in the cytoplasm of eukaryotic cells. Peroxisomes play a key role in the oxidation of specific biomolecules. They also contribute to the biosynthesis of membrane lipids known as plasmalogens. In plant cells, peroxisomes carry out additional functions.

Peroxisomes are small, membrane-enclosed organelles (Figure 10.24) that contain enzymes involved in a variety of metabolic reactions, including several aspects of energy metabolism.

Learn about peroxisomes, small vesicles that contain digestive and oxidative enzymes in eukaryotic cells. Find out how they metabolize lipids, reactive oxygen species and participate in photosynthesis and seed germination.

Peroxisomes are found in all eucaryotic cells. They contain oxidative enzymes, such as catalase and urate oxidase, at such high concentrations that in some cells the peroxisomes stand out in electron micrographs because of the presence of a crystalloid core (Figure 12-31).

Evidence for the existence of a multistep peroxisome assembly pathway that operates by the ordered conversion of structurally distinct peroxisomal subforms to mature peroxisomes.

Peroxisomes are single membrane-bound organelles that contain oxidative enzymes and catalase. They metabolize hydrogen peroxide, fatty acids, uric acid, and other substances in eukaryotic cells.

Peroxisome is an organelle conserved in almost all eukaryotic cells with a variety of functions in cellular metabolism, including fatty acid β-oxidation, synthesis of ether glycerolipid plasmalogens, and redox homeostasis.

A type of organelle found in both animal cells and plant cells, a peroxisome is a membrane-bound cellular organelle that contains mostly enzymes. Peroxisomes perform important functions, including lipid metabolism and chemical detoxification.

What are peroxisomes? In many publications, peroxisomes are introduced as ubiquitous, single-membrane-bound subcellular organelles that have a fine granular matrix and fulfil important metabolic functions in hydrogen peroxide and lipid metabolism and are therefore essential for human health and development.
