5. What is the difference of fatty acid β oxidation in mitochondrion versus
peroxisome? Why such a difference exists?
6. (a) Write down the structure of arachidonic acid (C20:4 Δ5,8,11,14).
(b) What do you expect of the melting point of arachidonic compared to that of arachidic acid
(C20:0) and why.
(c) Write down the second and third cycles of β-oxidation of
arachidonic acids including the corresponding enzymes.
(d) How many ATPs can be synthesized with the free energy generated from the oxidation of arachidonic acid? Show your calculation.
