Dzina la malonda:tannic acid

Tannic acid ndi mtundu wina wa tannin, mtundu wa polyphenol.Kuchepa kwake kwa acidity (pKa kuzungulira 6) kumachitika chifukwa cha magulu ambiri a phenol mu kapangidwe kake.Mankhwala opangira tannic acid nthawi zambiri amaperekedwa ngati C76H52O46, yomwe imagwirizana ndi glucose wa decagalloyl, koma kwenikweni ndi osakaniza a polygalloyl glucoses kapena polygalloyl quinic acid esters ndi chiwerengero cha galloyl moieties pa molekyulu kuyambira 2 mpaka 12 malingana ndi zomera zomwe zimagwiritsidwa ntchito pochotsa tannic acid.tannic acid wamalonda nthawi zambiri amachotsedwa pazigawo za zomera zotsatirazi: Tara pods (Caesalpinia spinosa), mtedza wa Rhus semialata kapena Quercus infectoria kapena masamba a Sicilian sumac.
