Metabolite Identification
Common Name2-Hydroxypurine
Description2-Hydroxypurine belongs to the class of organic compounds known as purinones. These are purines in which the purine moiety bears a C=O group. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Based on a literature review very few articles have been published on 2-Hydroxypurine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-hydroxypurine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Hydroxypurine 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.
