In the beta oxidation of unsaturated fatty acids with even-number position double bonds, the 2,4 dienoyl-CoA reductase uses NADPH to convert two conjugated double bonds into a single double bond. Desaturases use NADH in catalyzing the conversion of single bonds to double bonds.
a) Explain why this is a discrepancy
b) Why do the desaturase enzymes need NADH?
c) Which contains more extractable energy: an 18:0 or an 18:1 fatty acid?
