Common NameEstreptoquinasa
Description4-cyclohexylpyrrolidine-2-carboxylic acid 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 a significant number of articles have been published on 4-cyclohexylpyrrolidine-2-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Estreptoquinasa is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Estreptoquinasa 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.
