Metabolite Identification
Common Namephosphatidylinositol-4-phosphate
Descriptionphosphatidylinositol-4-phosphate belongs to the class of organic compounds known as glycerophosphoinositol phosphates. These are lipids containing a common glycerophosphate skeleton linked to at least one fatty acyl chain and an inositol-5-phosphate moiety. Based on a literature review a significant number of articles have been published on phosphatidylinositol-4-phosphate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phosphatidylinositol-4-phosphate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically phosphatidylinositol-4-phosphate 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.
