  <name>Epicatechin-(4beta-&gt;6)-catechin 3-gallate</name>
  <description>Epicatechin-(4beta-&gt;6)-catechin 3-gallate is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Epicatechin-(4beta-&gt;6)-catechin 3-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(4beta-&gt;6)-catechin 3-gallate can be found in common grape, which makes epicatechin-(4beta-&gt;6)-catechin 3-gallate a potential biomarker for the consumption of this food product.</description>
