Metabolite Identification
Common NameEthyl levulinate
DescriptionEthyl levulate, also known as fema 2442, belongs to the class of organic compounds known as gamma-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the C4 carbon atom. Ethyl levulate exists as a solid, soluble (in water), and an extremely weak acidic (essentially neutral) compound (based on its pKa). Within the cell, ethyl levulate is primarily located in the cytoplasm. Ethyl levulate exists in all eukaryotes, ranging from yeast to humans. Ethyl levulate has a sweet, berry, and floral taste.
