3-Hydroxyoctanoic acid is a beta-hydroxy acid that is naturally produced in humans, other animals, and plants.

3-Hydroxyoctanoic acid is the primary endogenous agonist of hydroxycarboxylic acid receptor 3 (HCA₃), a G protein-coupled receptor protein which is encoded by the human gene HCAR3.^[1]^[2] In plants, signalling chemical emitted by the orchid Cymbidium floribundum and recognized by Japanese honeybees (Apis cerana japonica).^[3]
