  <name>Glycitein</name>
  <description>Glycitein belongs to the class of organic compounds known as isoflavones. These are polycyclic compounds containing a 2-isoflavene skeleton which bears a ketone group at the C4 carbon atom. Thus, glycitein is considered to be a flavonoid lipid molecule. Glycitein is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.</description>
