Metabolite Identification
Common Name17(R)-HDoHE
Description17(R)-HDoHE, also known as 17-hydroxy-dha or 17(R)hdohe, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Based on a literature review a small amount of articles have been published on 17(R)-HDoHE. This compound has been identified in human blood as reported by (PMID: 31557052 ). 17(r)-hdohe is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 17(R)-HDoHE 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.
