| Description | methyl pyruvate belongs to the class of organic compounds known as alpha-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. Based on a literature review a significant number of articles have been published on methyl pyruvate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Methyl pyruvate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Methyl pyruvate 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. |
