| Description | Tannin belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. Tannin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, tannin is found, on average, in the highest concentration in a few different foods, such as nances, tea, and black walnuts and in a lower concentration in potato, common thymes, and papaya. Tannin has also been detected, but not quantified in, several different foods, such as coconuts, dandelions, roman camomiles, german camomiles, and figs. This could make tannin a potential biomarker for the consumption of these foods. |
