Basic structure of a peroxisome Distribution of peroxisomes (white) in HEK 293 cells during mitosis Peroxisome in rat neonatal cardiomyocyte. A peroxisome (/ p ə ˈ r ɒ k s ɪ ˌ s oʊ m /) [1] is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells. [2] [3] Peroxisomes are oxidative ...
A peroxisome is a type of microbody that functions to help the body break down large molecules and detoxify hazardous substances. It contains enzymes like oxidase, react hydrogen peroxide as a byproduct of its enzymatic reactions. Within the peroxisome, hydrogen peroxide can then be converted to water by enzymes like catalase and peroxidase.
These DNA sequences are termed PPREs (peroxisome proliferator hormone response elements). The DNA consensus sequence is AGGTCANAGGTCA, with N being any nucleotide . In general, this sequence occurs in the promoter region of a gene , and, when the PPAR binds its ligand, transcription of target genes is increased or decreased, depending on the gene.

Glyoxysomes are specialized peroxisomes found in plants (particularly in the fat storage tissues of germinating seeds) and also in filamentous fungi. Seeds that contain fats and oils include corn, soybean, sunflower, peanut and pumpkin. [1] As in all peroxisomes, in glyoxysomes the fatty acids are oxidized to acetyl-CoA by peroxisomal β ...
Glutathione Peroxidase 1 (Peroxidases or peroxide reductases (EC number 1.11.1.x) are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides, and should not be confused with other enzymes that produce peroxide, which are often oxidases.
WASHINGTON — White House adviser Alina Habba said Tuesday that military veterans affected by the DOGE-led layoffs of federal workers may not be "fit to have a job at this moment."
Peroxisomal disorders represent a class of medical conditions caused by defects in peroxisome functions. [1] This may be due to defects in single enzymes [2] important for peroxisome function or in peroxins, proteins encoded by PEX genes that are critical for normal peroxisome assembly and biogenesis.
