| Description | 3,4,5,19-tetramethoxy-9,10-dimethyl-15,17-dioxatetracyclo[10.7.0.0²,⁷.0¹⁴,¹⁸]nonadeca-1(19),2,4,6,12,14(18)-hexaen-9-ol 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. Based on a literature review very few articles have been published on 3,4,5,19-tetramethoxy-9,10-dimethyl-15,17-dioxatetracyclo[10.7.0.0²,⁷.0¹⁴,¹⁸]nonadeca-1(19),2,4,6,12,14(18)-hexaen-9-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Gomisin a is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Gomisin A 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. |
