Metabolite Identification
Common NameCalcein AM
DescriptionCalcein AM, also known as calcein-am, belongs to the class of organic compounds known as xanthenes. These are polycyclic aromatic compounds containing a xanthene moiety, which consists of two benzene rings joined to each other by a pyran ring. Based on a literature review a small amount of articles have been published on Calcein AM. This compound has been identified in human blood as reported by (PMID: 31557052 ). Calcein am is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Calcein AM 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.
