Hi I need help on a biochem study question.

To calculate the energy generated by the oxidation of a fatty acid Fatty acids yield more than twice as much energy per gram as carbohydrates. The image below shows the beta-oxidation pathway, a series of four reactions that oxidizes fatty acyl-SCoA to acetyl-SCoA. Note that the fatty acid converted to fatty acyl-SCoA, an energy-requiring process, before it enters the beta-oxidation pathway. The hydrocarbon tail of the fatty acid is represented by CH_2 atoms and the R group in acyl-SCoA. Energy is generated from the electrons of FADH2 and NADH that enter the electron transport chain and from the passage of acetyl-SCoA through the citric acid cycle. Part A Calculate the number of molecules of acetyl-SCoA derived from a saturated fatty acid with 12 carbon atoms.

Explanation / Answer

The number of acetyl CoA derived from a saturated fatty acid with 12 carbon atoms = n/2 = 12/2 = 6

Where n = number of carbon atoms.
