International audience. Alpha-linolenic acid (ALA) is abundant in plants and essential in human diet. Due tothe occurrence of skipped diene in the structure, it can steadily become oxidizednon-enzymatically in plants and human, and generate phytoprostanes (PhytoPs) andphytofurans (PhytoFs). Insofar, there are Type A-, B-, D-, E-, F-, J- and L-PhytoPs thatcomprises of different isomers, and two types of PhytoFs; the alkenyl and enediol substructuresidentified by analysts and synthesized by organic chemists. In agriculturalproducts such as olives and almonds, these compounds are valuable biomarkers for adverse environmental change and quality assurance. In plants they regulate immunologicalfunctions and take part in gene interaction for growth, while in human,they retain antioxidative and anti-inflammatory properties. This chapter introducesthe types of PhytoPs and PhytoFs found in ALA rich plants and algae, and overlooksat some potential biological functions in plants and human.
