Decanoyl-coenzyme A (CoA) is a thioester of decanoic acid and CoA .1 It inhibits the activity of citrate synthase (CS) and glutamate dehydrogenase (GDH) in mitochondria isolated from rat brain (IC50s = 437 and 420 µM, respectively).2 Decanoyl-CoA also binds the fatty acid metabolism regulator protein (FadR) promoter in E. coli (Ki = 2 µM).3 It is produced during isomerase-dependent β-oxidation of oleic acid in isolated rat heart mitochondria.4
