oxidation (i.e. metabolic disorders).

ACAD enzymes have been identified in animals (of which there are 9 major eukaryotic classes), as well as plants, nematodes, fungi, and bacteria. Five of these nine classes are involved in fatty acid ?-oxidation (SCAD, MCAD, LCAD, VLCAD, and VLCAD2), and the other four are involved in branched chain amino acid metabolism (i3VD, i2VD, GD, and iBD). Most acyl-CoA dehydrogenases are ?₄ homotetramers, and in two cases (for
