| Common Name | Pedunculagin |
|---|
| Description | Pedunculagin 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. Pedunculagin is found, on average, in the highest concentration within pomegranates (Punica granatum). Pedunculagin has also been detected, but not quantified in, several different foods, such as red tea, walnuts (Juglans), green tea, acorns (Quercus), and red raspberries (Rubus idaeus). This could make pedunculagin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Pedunculagin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pedunculagin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pedunculagin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
