  <name>Thymusin</name>
  <description>Thymusin is a member of the class of compounds known as 8-o-methylated flavonoids. 8-o-methylated flavonoids are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, thymusin is considered to be a flavonoid lipid molecule. Thymusin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Thymusin can be found in peppermint, which makes thymusin a potential biomarker for the consumption of this food product. </description>
