Common Name | 3-Methylthymine |
---|
Description | 3-Methylthymine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 3-Methylthymine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 3-Methylthymine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-methylthymine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Methylthymine 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. |
