S-adenosyl-4-methylthio-2-oxobutanoic acid is a member of the class of compounds known as 5-deoxy-5-thionucleosides. 5-deoxy-5-thionucleosides are 5-deoxyribonucleosides in which the ribose is thio-substituted at the 5position by a S-alkyl group. S-adenosyl-4-methylthio-2-oxobutanoic acid is practically insoluble (in water) and a moderately acidic compound (based on its pKa). S-adenosyl-4-methylthio-2-oxobutanoic acid can be found in a number of food items such as hard wheat, chinese cabbage, cauliflower, and kai-lan, which makes S-adenosyl-4-methylthio-2-oxobutanoic acid a potential biomarker for the consumption of these food products. S-adenosyl-4-methylthio-2-oxobutanoic acid exists in E.coli (prokaryote) and yeast (eukaryote).
