Metabolite Identification
Common NameParasorbic acid
DescriptionParasorbic acid, also known as parasorbate, is a member of the class of compounds known as dihydropyranones. Dihydropyranones are compounds containing a hydrogenated pyran ring which bears a ketone, and contains one double bond. Parasorbic acid is soluble (in water) and an extremely weak acidic compound (based on its pKa). Parasorbic acid can be found in american cranberry and rowanberry, which makes parasorbic acid a potential biomarker for the consumption of these food products. Parasorbic acid is the cyclic lactone of sorbic acid. Thermal treatment or hydrolysis converts the lactone to sorbic acid .
