描述
3,4,5,11,14,20,21,22-octahydroxy-13-(hydroxymethyl)-9,12,16-trioxatetracyclo[16.4.0.0²,⁷.0¹⁰,¹⁵]docosa-1(22),2,4,6,18,20-hexaene-8,17-dione is a member of the class of compounds known as hydrolyzable tannins. Hydrolyzable tannins 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) 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. 3,4,5,11,14,20,21,22-octahydroxy-13-(hydroxymethyl)-9,12,16-trioxatetracyclo[16.4.0.0²,⁷.0¹⁰,¹⁵]docosa-1(22),2,4,6,18,20-hexaene-8,17-dione is soluble (in water) and a very weakly acidic compound (based on its pKa). 3,4,5,11,14,20,21,22-octahydroxy-13-(hydroxymethyl)-9,12,16-trioxatetracyclo[16.4.0.0²,⁷.0¹⁰,¹⁵]docosa-1(22),2,4,6,18,20-hexaene-8,17-dione can be found in pomegranate, which makes 3,4,5,11,14,20,21,22-octahydroxy-13-(hydroxymethyl)-9,12,16-trioxatetracyclo[16.4.0.0²,⁷.0¹⁰,¹⁵]docosa-1(22),2,4,6,18,20-hexaene-8,17-dione a potential biomarker for the consumption of this food product.
