Common_Name4,8 dimethylnonanoyl carnitine
Description4,8 dimethylnonanoyl carnitine is not a substrate for carnitine acetyltransferase, another acyltransferase localized in peroxisomes, which catalyzes the formation of carnitine esters of the other products of pristanic acid beta-oxidation, namely acetyl-CoA and propionyl-CoA. (PMID: 10486279) In normal cells, 4,8-dimethylnonanoylcarnitine (C11:0) and 2,6-dimethylheptanoylcarnitine (C9:0) accumulated after incubation with either phytanic acid or pristanic acid.(PMID: 9469587) Earlier studies have shown that pristanic acid undergoes three cycles of beta-oxidation in peroxisomes to produce 4,8-dimethylnonanoyl-CoA (DMN-CoA) which is then transported to the mitochondria for full oxidation to CO(2) and H(2)O. In principle, this can be done via two different mechanisms in which DMN-CoA is either converted into the corresponding carnitine ester or hydrolyzed to 4,8-dimethylnonanoic acid plus CoASH.(PMID: 11785945)
