Metabolite Identification
Common NameD,L-Buthionine
DescriptionD,L-Buthionine belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Based on a literature review a significant number of articles have been published on D,L-Buthionine. This compound has been identified in human blood as reported by (PMID: 31557052 ). D,l-buthionine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically D,L-Buthionine 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.
