Tannic acid (CAS 1401-55-4) is a polyphenolic compound classified among hydrolyzable tannins commonly extracted from plant sources such as oak galls It functions as a weak acid and exhibits protein-precipitating activity through non-specific binding to proteins and other macromolecules Tannic acid s ability to modulate protein interactions underlies its astringent antimicrobial and anti-inflammatory properties making it useful in research on barrier protection wound healing and inhibition of pathogenic microorganisms Additionally it is studied for its role in modulating cell adhesion oxidative stress and as an experimental agent in gastrointestinal and dermatological models
