| Description | Phaseic 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 . |
