Peroxisomes and Its Functions

Peroxisomes or microbodies are the membrane minimal vesicles like the lysosomes. Unlike lysosomes, peroxisomes are pinched off from endoplasmic reticulum and not from the Golgi apparatus Peroxisomes consist of some oxidative enzymes such as catalase, urate oxidase and D-amino acid oxidase.


Oxidative enzymes, as the name suggests, utilize oxygen (02), in this case to strip hydrogen from specific natural molecules This reaction assists cleanse numerous wastes produced within the cell or foreign poisonous substances that have actually gotten in the cell, such as alcohol consumed in drinks.

The significant product created in the peroxisome, hydrogen peroxide (H202), is formed by molecular oxygen and the hydrogen atoms removed from the poisonous molecule Hydrogen peroxide is possibly damaging if enabled to build up or leave from the boundaries of the peroxisome. Nevertheless, peroxisomes likewise consist of an abundance of catalase, an enzyme that disintegrates powerful H202 into safe H20 and 02. This latter reaction is a crucial security mechanism that ruins the possibly fatal peroxide at its site of production, consequently avoiding its possible destructive escape into the cytosol.

Functions of Peroxisomes


  1. Breakdown the fats by ways of a process called beta-oxidation: This is the significant function of peroxisomes
  2. Deteriorate the poisonous substances such as hydrogen peroxide and other metabolic products by ways of detoxing. A a great deal of peroxisomes exist in the cells of liver, which is the significant organ for detoxing. Hydrogen peroxide is formed from toxins or alcohol, which get in the cell. Whenever hydrogen peroxide is produced in the cell, the peroxisomes are burst and the oxidative enzymes are launched. These oxidases damage hydrogen peroxide and the enzymes which are required for the production of hydrogen peroxide
  3. Form the significant site of oxygen usage in the cells
  4. Speed up gluconeogenesis from fats
  5. Deteriorate purine to uric acid
  6. Take part in the formation of myelin
  7. Play a role in the formation of bile acids.
