| Common Name | 3-O-Acetyloleanolic acid |
|---|
| Description | 10-(acetyloxy)-2,2,6a,6b,9,9,12a-heptamethyl-1,2,3,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,12b,13,14b-icosahydropicene-4a-carboxylic acid belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Based on a literature review very few articles have been published on 10-(acetyloxy)-2,2,6a,6b,9,9,12a-heptamethyl-1,2,3,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,12b,13,14b-icosahydropicene-4a-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-o-acetyloleanolic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-O-Acetyloleanolic acid 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. |
