Metabolite Identification
Common NamePhaseic acid
DescriptionPhaseic acid, also known as phaseate, belongs to abscisic acids and derivatives class of compounds. Those are terpene compounds containing the abscisic acid moiety, which is characterized by a 3-methylpenta-2,4-dienoic acid attached to the C1 carbon of a 4-oxocyclohex-2-ene moiety. Phaseic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Phaseic acid can be found in a number of food items such as boysenberry, prunus (cherry, plum), european plum, and wild rice, which makes phaseic acid a potential biomarker for the consumption of these food products. Phaseic acid is a terpenoid catabolite of abscisic acid. Like abscisic acid, it is a plant hormone associated with photosynthesis arrest and abscission .
