Metabolite Identification

Common Name

(2R,4S)-Pyrrolidine-2,4-dicarboxylic acid

Description

(2R,4S)-Pyrrolidine-2,4-dicarboxylic acid, also known as 2,4-pyrrolidinedicarboxylate or PDC-2,4, belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives are compounds containing proline or a derivative thereof resulting from reaction of proline at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Based on a literature review very few articles have been published on (2R,4S)-Pyrrolidine-2,4-dicarboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2r,4s)-pyrrolidine-2,4-dicarboxylic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2R,4S)-Pyrrolidine-2,4-dicarboxylic acid 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.
