Metabolite Identification
Common NameN-Cyclohexyltaurine
DescriptionN-cyclohexyltaurine, also known as CHES, belongs to the class of organic compounds known as cyclohexylamines. These are organic compounds containing a cyclohexylamine moiety, which consist of a cyclohexane ring attached to an amine group. N-cyclohexyltaurine is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). N-cyclohexyltaurine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Cyclohexyltaurine 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.
