Chemical Information
FooDB NameWyerone acid
Description(2e,11z)-wyerone acid is a member of the class of compounds known as furanoid fatty acids. Furanoid fatty acids are fatty acids containing a 5-alkylfuran-2-alkanoic acid (2e,11z)-wyerone acid is practically insoluble (in water) and a moderately acidic compound (based on its pKa). (2e,11z)-wyerone acid can be found in pulses, which makes (2e,11z)-wyerone acid a potential biomarker for the consumption of this food product.
