  <name>(11R,12S,13S)-Epoxy-hydroxyoctadeca-cis-9-cis-15-dien-1-oic acid</name>
  <description>(11r,12s,13s)-epoxy-hydroxyoctadeca-cis-9-cis-15-dien-1-oic acid is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms (11r,12s,13s)-epoxy-hydroxyoctadeca-cis-9-cis-15-dien-1-oic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). (11r,12s,13s)-epoxy-hydroxyoctadeca-cis-9-cis-15-dien-1-oic acid can be found in rice, which makes (11r,12s,13s)-epoxy-hydroxyoctadeca-cis-9-cis-15-dien-1-oic acid a potential biomarker for the consumption of this food product. </description>
