Question

Calculate the number of repetitions of the beta-oxidation pathway required to fully convert a 14-carbon activated fatty acid to acetyl-SCoA molecules. Calculate the number of acetyl-SCoA molecules generated by complete beta oxidation of a 14-carbon activated fatty acid. An acetyl group (containing two carbon atoms) is split off the original fatty acyl-SCoA with each repetition of the beta-oxidation spiral. Therefore, the first repetition of the beta-oxidation spiral yields one acetyl-SCoA molecule and a fatty acyl-SCoA molecule that is two carbon atoms shorter than the initial fatty acyl-SCoA. Consider the number of acetyl-SCoA molecules produced by the sixth repetition.

Explanation / Answer

With each round of oxidation, one acetyl coA is released from the fatty acid chain. During the sixth round of beta oxidation, only four carbons are left. Release of one acetyl coA leaves the other two carbons with coA attached to them.

Therefore, the total rounds of oxidation are 6.

The total number of acetyl coA generated are half that of the total no of cargons in the even numbered carbon chain. Therefore, the answer is 7.
