  <name>Theaspirone</name>
  <description>Theaspirone a is a member of the class of compounds known as cyclohexenones. Cyclohexenones are compounds containing a cylohexenone moiety, which is a six-membered aliphatic ring that carries a ketone and has one endocyclic double bond. Theaspirone a is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Theaspirone a can be found in tea, which makes theaspirone a a potential biomarker for the consumption of this food product. </description>
