Metabolite Identification

Common Name

2-(N-Morpholino)-ethanesulfonic acid

Description

2-(N-Morpholino)-ethanesulfonic acid, also known as 2-(N-morpholino)aethansulfonsaeure or 4-morpholineethanesulphonate, belongs to the class of organic compounds known as morpholines. These are organic compounds containing a morpholine moiety, which consists of a six-member aliphatic saturated ring with the formula C4H9NO, where the oxygen and nitrogen atoms lie at positions 1 and 4, respectively. Based on a literature review a significant number of articles have been published on 2-(N-Morpholino)-ethanesulfonic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(n-morpholino)-ethanesulfonic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(N-Morpholino)-ethanesulfonic 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.
