Metabolite Identification
Common NameD-Threonine
Descriptionalpha-Amino-beta-hydroxybutyric acid, also known as a-amino-b-hydroxybutyrate, 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). alpha-Amino-beta-hydroxybutyric acid has been detected, but not quantified in, peanuts (Arachis hypogaea). This could make alpha-amino-beta-hydroxybutyric acid a potential biomarker for the consumption of these foods. alpha-Amino-beta-hydroxybutyric acid 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 very few articles have been published on alpha-Amino-beta-hydroxybutyric acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). D-threonine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically D-Threonine 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.
