Minquartynoic acid is an unsaturated, conjugated, and hydroxylated fatty acid containing four triple bonds and belonging to the class of polyyne and alkynoic acids. It was only discovered in 1989. The acid is optically active, but there are conflicting data regarding the rotation of the natural S-isomer.
