  <name>psi-Taraxasterol</name>
  <description>Psi-taraxasterol is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Psi-taraxasterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Psi-taraxasterol can be found in burdock and dandelion, which makes psi-taraxasterol a potential biomarker for the consumption of these food products. </description>
