Common Name | Castanin |

Description | Castanin, also known as 2-BDBP or tomentosin?, 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. Castanin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, castanin has been detected, but not quantified in, fruits and nuts. This could make castanin a potential biomarker for the consumption of these foods. |
