Peroxisomes Definition: Peroxisomes are otherwise known as microbodies. They are single-membrane vesicles of regarding 0.5 millimeters in diameter. They contain an enzyme, D-amino acid enzyme, salt enzyme, and alternative aerophilous enzymes. Peroxisomes contain a range of enzymes, that primarily operate along to rid of the cell of cyanogenetic substances, and especially, oxides. Peroxisomes Structure Described Below:
They are single – membrane organelles. Peroxisomes are the vesicles of about 0.5 mm in diameter. These organelles contain enzymes that convert the peroxide to water, rendering the possibly cyanogenic substance safe for unleashing back to the cell.

Some sorts of peroxisomes, like those in liver cells, detoxify alcohol and other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (a process termed oxidation). Others square measure additional necessary for his or her ability to initiate the assembly of phospholipids, that square measure generally utilized in the formation of membranes.
- Peroxisomes microbodies participate in the oxidation of various nutrients.
- In these organelles, toxic compound Hydrogen Peroxide reduction occurs and produces oxygen.
- Oxygen produced by the reduction of Hydrogen Peroxide is decomposed and water form.
- Lipids metabolism takes place in Peroxisomes.
- They are important in the human body as well.
- Peroxisomes help in the oxidation of fatty acids that are greater in length than 18 carbons.
- All type of fatty acid oxidation takes place in peroxisomes of Yeast.
- Peroxisomes play a vital role in the Beta – Oxidation.
- Beta – Oxidation is the process in which fatty acid molecules breakdown process occurs. In this process, the molecules of fatty acids are broken down into Acetyl-CoA which are then transported to the cytosol.
- Peroxisomes play an integral role in the synthesis of the Myelin Sheath.
- Peroxisomes consist of enzymes which are required for the Plasmalogens synthesis.
- Cholesterol and Bile acid synthesis takes place in Peroxisomes.
- Peroxisomes are also responsible for the catabolism of purine and polyamine catabolism.
- They also help in prostaglandin metabolism.
- Peroxisomes in plants necessary for photorespiration.
