Metabolite Identification
Common Name2-Iodohippuric acid
Description2-iodohippuric acid, also known as iodohippate or O-iodobenzoylglycine, belongs to the class of organic compounds known as hippuric acids. Hippuric acids are compounds containing hippuric acid, which consists of a of a benzoyl group linked to the N-terminal of a glycine. Based on a literature review a significant number of articles have been published on 2-iodohippuric acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-iodohippuric acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Iodohippuric 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.
