Functional groups in tannic acid are the phenolic -OH groups.

Tannic acid is a specific commercial form of tannin, a type of polyphenol. Its weak acidity (pKa around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C76H52O46

A sketch of its formula is found in 'Related links' below this answer.
