Metabolite Identification
Common Nameisosorbide
DescriptionIsomannide belongs to the class of organic compounds known as isosorbides. These are organic polycyclic compounds containing an isosorbide(1,4-Dianhydrosorbitol) moiety, which consists of two -oxolan-3-ol rings. Isomannide is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Isosorbide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically isosorbide 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.
