Chemical Information
FooDB NameBrevifolincarboxylic acid
DescriptionBrevifolincarboxylic acid belongs to isocoumarins and derivatives class of compounds. Those are polycyclic compounds containing an isochromane which bears a ketone at the carbon C1. Brevifolincarboxylic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Brevifolincarboxylic acid can be found in pomegranate, which makes brevifolincarboxylic acid a potential biomarker for the consumption of this food product.
