Metabolite Identification
Common NamePenem
DescriptionPenem belongs to the class of organic compounds known as penems. These are organic heterocyclic compounds containing a penem moiety, which is a 2,3-didehydropenam derivative. Based on a literature review a significant number of articles have been published on Penem. This compound has been identified in human blood as reported by (PMID: 31557052 ). Penem is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Penem 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.
