Elaidic acid is the major trans fat found in hydrogenated vegetable oils and can be used as a pharmaceutical solvent.

cis-Vaccenic acid, the antiviral extract from Rhodopseudomonas capsulate and the predominant active component of Rhodopseudomonas capsulate, acts a potential fetal hemoglobin inducer.

trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level.

Ricinoleic acid, a hydroxy fatty acid, is an attractive feedstock for the production of high-performance lubricants, cosmetics, polymers, surfactants, and coatings.

Ricinelaidic acid is a 12-hydroxy fatty acid and an antagonist of leukotriene B4 (LTB4) receptors (Ki = 2 µM in porcine neutrophil membranes). It inhibits chemotaxis and calcium flux induced by LTB4 in isolated human neutrophils (IC50s = 10 and 7 µM, respectively). Ricinelaidic acid (1 mg/kg, i.v.) inhibits bronchoconstriction induced by LTB4 in rats by 46%.
