Metabolite Identification

Common Name

2-Oxo-4-methylthiobutanoic acid

Description

4-Methylthio-2-oxobutanoate, also known as 2-keto-4-methylthiobutyrate or 2-oxomethionine, belongs to the class of organic compounds known as thia fatty acids. These are fatty acid derivatives obtained by insertion of a sulfur atom at specific positions in the chain. 4-Methylthio-2-oxobutanoate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 4-Methylthio-2-oxobutanoate exists in all living species, ranging from bacteria to humans.
