Metabolite Identification
Common NameAlloxazine
DescriptionAlloxazine belongs to the class of organic compounds known as alloxazines and isoalloxazines. These are organic compounds comprising the (iso)alloxazine structure (Benzo[g]pteridine-2,4-dione). Based on a literature review a significant number of articles have been published on Alloxazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alloxazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Alloxazine 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.
