Octanoyl-CoA+FAD<=>trans-Oct-2-enoyl-CoA+FADH2 At the beginning of this reaction, 1 molecule of 'Octanoyl-CoA', and 1 molecule of 'FAD' are present. At the end of this reaction, 1 molecule of 'FADH2', and 1 molecule of 'trans-Oct-2-enoyl-CoA' are present.<br><br> This reaction takes place in the 'mitochondrial matrix' and is mediated by the 'acyl-CoA dehydrogenase activity' of 'MCAD acyl-CoA dehydrogenase homotetramer'.<br> EC Number: 1.3.99.3 Pubmed13295225 Pubmed3597357 Reactome Database ID Release 4377338 Reactome, http://www.reactome.org ReactomeREACT_442
