Definition

2-oxo-4-methylthiobutanoic acid, also known as 2-keto-4-methylthiobutyrate or 4-methylthio-2-oxobutanoate, is a member of the class of compounds known as thia fatty acids. Thia fatty acids are fatty acid derivatives obtained by insertion of a sulfur atom at specific positions in the chain. Thus, 2-oxo-4-methylthiobutanoic acid is considered to be a fatty acid lipid molecule. 2-oxo-4-methylthiobutanoic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 2-oxo-4-methylthiobutanoic acid can be synthesized from L-methionine and butyric acid. 2-oxo-4-methylthiobutanoic acid can also be synthesized into S-adenosyl-4-methylthio-2-oxobutanoic acid. 2-oxo-4-methylthiobutanoic acid can be found in a number of food items such as leek, hickory nut, brussel sprouts, and giant butterbur, which makes 2-oxo-4-methylthiobutanoic acid a potential biomarker for the consumption of these food products. 2-oxo-4-methylthiobutanoic acid can be found primarily in urine. 2-oxo-4-methylthiobutanoic acid exists in all living species, ranging from bacteria to humans. In humans, 2-oxo-4-methylthiobutanoic acid is involved in the methionine metabolism. 2-oxo-4-methylthiobutanoic acid is also involved in several metabolic disorders, some of which include s-adenosylhomocysteine (SAH) hydrolase deficiency, homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type, glycine n-methyltransferase deficiency, and cystathionine beta-synthase deficiency.
