Metabolite Identification
Common NameHomofureanol
DescriptionHomofureanol belongs to the class of organic compounds known as furanones. Furanones are compounds containing a furan ring bearing a ketone group. Homofureanol is a sweet, butterscotch, and candy tasting compound. Homofureanol has been detected, but not quantified in, several different foods, such as sorghums (Sorghum bicolor), sweet oranges (Citrus sinensis), silver lindens (Tilia argentea), horseradishes (Armoracia rusticana), and green bell peppers (Capsicum annuum). This could make homofureanol a potential biomarker for the consumption of these foods. Homofureanol 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 a significant number of articles have been published on Homofureanol.
