Secondary Accession NumbersNone
Metabolite Identification
Common NameThiazine
DescriptionThiazine belongs to the class of organic compounds known as 1,2-thiazines. These are organic compounds containing 1,2-thiazine, a six-member ring with a nitrogen and a sulfur atoms in ring positions 1 and 2 respectively, as well as two double bonds. Based on a literature review a significant number of articles have been published on Thiazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Thiazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Thiazine 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.
