Question

Quizplus · Accepted Answer

The most common naturally occurring fatty acids have 12-20 carbon atoms and an even number of carbon atoms. This is because they are synthesized from acetyl CoA, which contains two carbon atoms, and the synthesis of fatty acids involves multiple rounds of adding two-carbon units. This results in fatty acids with an even number of carbon atoms, and the range of 12-20 carbon atoms is the most common length for these fatty acids.
