Palustric acid is an organic compound with the formula C20H30O2. It is classified as a diterpenoid (a C20 hydrocarbon with oxygenated groups) and a resin acid. Palustric acid is an isomer of abietic acid: the location of the two C=C bonds differ in these two compounds. [1] It is a colorless solid that is soluble in polar organic solvents. In terms of biological function palustric acid protects its host trees, especially conifers, against insects, an example of plant defense against herbivory. It is biosynthesized from the C20 precursor geranylgeranyl diphosphate. [2]
Palustric acid is very poorly soluble in water and has low acute toxicity. [3]
