Tannic acid is formed by the condensation of a glucose molecule and five digallic acid molecules, in turn formed by esterification of two molecules of gallic acid.
The phenolic groups present in the molecular structure give the tannic acid a slight acidity (pKa 10). Tannic acid reacts with strong bases to sleep salts called tannins.
Furthermore, tannic acid is the form in which tannin, a polyphenol, is marketed.
