Peroxisomale beta oxidation
In biochemistry and metabolism, beta oxidation (also β-oxidation) is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are co-enzymes used in the electron transport chain. It is named as such because the beta carbon of th… WebDec 8, 2014 · Peroxisomal β-oxidation is activated during senescence, where it is thought to have a role in the turnover of lipids derived from membranes of various organelles (Mano and Nishimura, 2005). The expression of most genes encoding peroxisomal proteins involved in β-oxidation is up-regulated during senescence (Supplemental Fig. S5).

WebAcetyl CoA is generated from fatty acids through repeated beta-oxidation cycles. Sets of 4 enzymes (an acyl dehydrogenase, a hydratase, a hydroxyacyl dehydrogenase, and a lyase) specific for different chain lengths (very long chain, long chain, medium chain, and short chain) are required to catabolize fatty acids completely.
