Metabolite Identification
Common Name17-Estradiol cyclooctyl acetate
Description17-Estradiol cyclooctyl acetate belongs to the class of organic compounds known as steroid esters. Steroid esters are compounds containing a steroid moiety which bears a carboxylic acid ester group. Based on a literature review a small amount of articles have been published on 17-Estradiol cyclooctyl acetate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 17-estradiol cyclooctyl acetate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 17-Estradiol cyclooctyl acetate 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.
