Tannins are water-soluble polyphenols found in a variety of plant foods.Tannic acid(TA) is a type of polyphenol and a specific kind of tannin. Because of the various phenol groups in the structure, it has low acidity (pKa about 6). C76H52O46is a popular chemical formula for commercial ...
1999. Chemopreventive activity of very low dose dietary tannic acid administration in hepatoma bearing C3H male mice. Cancer Letters. 141. 57.Nepka, C.; Sivridis, E.; Antonoglou, O.; Kortsaris, A.; Georgellis, A.; Taitzoglou, I.; Hytiroglou, P.; Papadimitriou, C.; Zintzaras,...
Increasing evidence supports the hypothesis that tannic acid, a plant polyphenol, exerts anticarcinogenic activity in chemically induced cancers. In the present study, tannic acid was found to strongly inhibit tyrosine kinase activity of epidermal growth factor receptor (EGFr) in vitro (IC50 = 323 nM...

Therefore, the doped tannic acid molecules exist dominantly as anions if the solution pH is above pH 3.7, and at pH 2.8, part of doped tannic acid has been deprotonated, implying that the pKa value of the doped tannic acid is smaller than 3.7. Third, the ∆f0, ∆R1 and current ...
To evaluate the impact of the protonation state, gallic acid was simulated in its two major protonation states, namely the fully protonated one (the neutral form denoted COOH) and the deprotonated one (the anion form denoted COO-). The deprotonation was at the carboxyl group, as the pKa of...
