Metabolite Identification
Common Name1-Hydroxy-2-butanone
Description1-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. A primary alpha-hydroxy ketone that is butane-1,2-diol in which the hydroxy group at position 2 has been formally oxidised to give the corresponding ketone. 1-Hydroxy-2-butanone is an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Hydroxy-2-butanone is a sweet, butterscotch, and coffee tasting compound. Outside of the human body, 1-Hydroxy-2-butanone has been detected, but not quantified in, coffee and coffee products and mushrooms. 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.
