• To calculate the energy produced from any fatty acid we should determine the # of carbons = n
• Then determine the # of turns (in even # saturated FAs it equals = "# − 1
 • Calculate energy produced in each turn which equal 17 ATPs .
• Add energy produced from one last acetyl CoA molecule which = 12 ATPs.
• Then subtract 2 ATPs which has been used in the step of fatty acid activation.
• Subtract energy produced from FADH2 did not consumed as FA is unsaturated.
