reply: six cycles
rationalization: The primary cycle of fatty acid synthesis yields a four-carbon acyl group. Every subsequent cycle provides a three-carbon malonyl group, which provides off one molecule of CO2 (one carbon atom) in a condensation response. Due to this fact, the web variety of carbon atoms added by every subsequent cycle is 2. As a result of the primary cycle produces a four-carbon chain, and every further cycle lengthens the chain by two carbon atoms, the second cycle ends in a six-carbon chain, the third cycle ends in an eight-carbon chain, and so forth. Due to this fact, the synthesis of the 14-carbon myristic acid requires six repetitions.
