Helenynolic acid is a hydroxylated and conjugated unsaturated fatty acid containing both a double and a triple bond. The acid belongs to the class of alkyne and alkenoic acids, as well as to the enynes. It is optically active with a negative rotation, i.e., levorotatory.

The delta notation is S-9-OH-18:2Δ10t,12a.
