Peroxisomes are ubiquitous organelles in eukaryotes that participate in the metabolism of fatty acids and other metabolites. Peroxisomes have enzymes that rid the cell of toxic peroxides.
s are ubiquitous organelles in eukaryotes. They consist of a single membrane that separates them from the cytosol (the internal fluid of the cell). s were discovered by Christian de Duve in 1965.

s - Another Enzyme Package
There are many ways that s are similar to lysosomes. They are small vesicles found around the cell.
Microbodies are a diverse group of organelles that are found in the cytoplasm of almost all cells, roughly spherical, and bound by a single membrane.
s are about the size of lysosomes (0.5-1.5 µm) and like them are bound by a single membrane. They also resemble lysosomes in being filled with enzymes.
Cell organelle containing enzymes involved in the production or destruction of hydrogen peroxide (H2O2).

Small organelle in eukaryotic cells whose functions include degradation of fatty acids and amino acids by means of reactions that generate hydrogen peroxide, which is converted to water and oxygen by catalase.
Peroxisome: Peroxisomes are membrane-bound packets of oxidative enzymes. In plant cells, peroxisomes play a variety of roles including converting fatty acids to sugar and assisting chloroplasts in photorespiration.

A microbody found in leaves and often associated with chloroplasts.
For example, 3 of the 11 genes predicted in the category 'acyl-CoA/fatty acid/peroxisome' encode a short-chain dehydrogenase motif, suggesting that they are metabolic enzymes.
The proteins found in the nucleus, mitochondria, chloroplasts, cytoplasm, and s are all synthesized on free ribosomes in the cytoplasm and not on the RER.
