Metabolite Identification
Common Name1-Hydroxy-2-pentanone
Description1-Hydroxy-2-pentanone belongs to the class of organic compounds known as monosaccharides. Monosaccharides are compounds containing one carbohydrate unit not glycosidically linked to another such unit, and no set of two or more glycosidically linked carbohydrate units. Monosaccharides have the general formula CnH2nOn. 1-Hydroxy-2-pentanone is an extremely weak basic (essentially neutral) compound (based on its pKa). These are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon.
