Question

Quizplus · Accepted Answer

The long chain of 26 carbons bonded together with a methyl group at one end and an acid group at the other end is characteristic of a fatty acid. The lack of nitrogen or sulfur atoms excludes options A and B, which require at least one of these elements. Option D, a sterol, typically contains a four-ring structure, which is not present in this compound.
