C15H21O5 (281.1389)


Dihydroxyphaseic acid is also known as dihydroxyphaseate. Dihydroxyphaseic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Dihydroxyphaseic acid can be found in a number of food items such as olive, turmeric, macadamia nut, and shiitake, which makes dihydroxyphaseic acid a potential biomarker for the consumption of these food products.
