描述
Pterocarinin a 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. Pterocarinin a is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Pterocarinin a can be found in cloves, which makes pterocarinin a a potential biomarker for the consumption of this food product.
