Chemical Information

FooDB Name

1-Hydroxy-2-butanone

Description

1-Hydroxy-2-butanone, also known as 2-oxobutanol or fema 3173, belongs to the class of organic compounds known as alpha-hydroxy ketones. These are organic compounds containing a carboxylic acid, and an amine group attached to the alpha carbon atom, relative to the C=O group. 1-Hydroxy-2-butanone is a sweet, butterscotch, and coffee tasting compound. 1-Hydroxy-2-butanone has been detected, but not quantified in, several different foods, such as robusta coffees (Coffea canephora), mushrooms, arabica coffees (Coffea arabica), coffee and coffee products, and oyster mushrooms (Pleurotus ostreatus). This could make 1-hydroxy-2-butanone a potential biomarker for the consumption of these foods. 1-Hydroxy-2-butanone, with regard to humans, has been linked to the inborn metabolic disorder celiac disease. Based on a literature review very few articles have been published on 1-Hydroxy-2-butanone.
