Metabolite Identification
Common NameEthyl isovalerate
DescriptionEthyl 3-methyl butanoate, also known as ethyl 3-methylbutyric acid or ethyl isopentanoate, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. Ethyl 3-methyl butanoate exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Ethyl 3-methyl butanoate exists in all eukaryotes, ranging from yeast to humans.
