Metabolite Identification
Common NameCystamine
Descriptioncystamine, also known as decarboxycystine, belongs to the class of organic compounds known as dialkyldisulfides. These are organic compounds containing a disulfide group R-SS-R' where R and R' are both alkyl groups. Based on a literature review a significant number of articles have been published on cystamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Cystamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cystamine 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.
