    basic FUNCTION
  • participating in catalyzing the initial step of the mitochondrial fatty acid beta-oxidation
  • shuttling electrons between primary flavoprotein dehydrogenases and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase
  • serving as a specific electron acceptor for several dehydrogenases, including five acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase
  • transferring the electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase)
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS electron transport
    PATHWAY
