Metabolite Identification
Common Name3-Oxooctanoyl-CoA
Description3-Oxooctanoyl-CoA is the substrate of the acetyl-CoA C-acyltransferase/oxoacyl-CoA thiolase A (EC 2.3.1.16, SCP2/3-oxoacyl-CoA thiolase) present in peroxisomes from normal liver. Peroxisomes beta -oxidize a wide variety of substrates including straight chain fatty acids, 2-methyl-branched fatty acids, and the side chain of the bile acid intermediates di- and trihydroxycoprostanic acids. Peroxisomes contain several beta -oxidation pathways with different substrate specificities; or example, straight chain acyl-CoAs are desaturated by palmitoyl-CoA oxidase, and their enoyl-CoAs are then converted to 3-oxoacyl-CoAs by MFP-1, which forms (hydration) and dehydrogenates L-3(3S)-hydroxyacyl-CoAs; for example, straight chain acyl-CoAs are desaturated by palmitoyl-CoA oxidase (23), and their enoyl-CoAs are then converted to 3-oxoacyl-CoAs by 3-hydroxyacyl-CoA dehydrogenase (EC 1.1.1.35), which forms (hydration) and dehydrogenates L-3(3S)-hydroxyacyl-CoAs and their enoyl-CoAs are then converted to the corresponding 3-oxoacyl-CoAs by long-chain-enoyl-CoA hydratase(EC 4.2.1.74), which forms and dehydrogenates D-3(3R)-hydroxyacyl-CoAs.
