Metabolite Identification

Common Name

Ethyl (±)-3-hydroxyhexanoate

Description

Ethyl (±)-3-hydroxyhexanoate 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-hydroxyhexanoate is a citrus, fresh, and fruity tasting compound. Ethyl (±)-3-hydroxyhexanoate is found, on average, in the highest concentration within red wine. Ethyl (±)-3-hydroxyhexanoate has also been detected, but not quantified in, several different foods, such as alcoholic beverages, asian pears (Pyrus pyrifolia), citrus, and fruits. This could make ethyl (±)-3-hydroxyhexanoate a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Ethyl (±)-3-hydroxyhexanoate.
