Metabolite Identification
Common NameEthyl (±)-3-hydroxybutyrate
DescriptionEthyl (±)-3-hydroxybutyrate, also known as ethyl b-hydroxybutyric acid, belongs to the class of organic compounds known as beta hydroxy acids and derivatives. Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. Ethyl (±)-3-hydroxybutyrate 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 Ethyl (±)-3-hydroxybutyrate.
