How many cycles of the synthesis pathway are needed to produce myristic acid, c13h27cooh?

The primary cycle of fatty acid synthesis produces a four-carbon acyl group. Every following cycle adds a three-carbon malonyl group, which stretches off one molecule of CO2 (one carbon atom) in a condensation response. Thus, the net number of carbon atoms additional by each following cycle is two. For the reason that the first cycle makes a four-carbon chain, and each added cycle extends the chain by two carbon atoms, the second cycle fallouts in a six-carbon chain, the third cycle fallouts in an eight-carbon chain, and so on. And so, the synthesis of the 14-carbon myristic acid necessitates six repetitions.
