General description
α-Keto-γ-methylthiobutyric acid (KMTB) is a keto derivative of L-methionine that shows considerable potential as a substitute for L-methionine. The sodium salt of KMTB can be employed in nucleophilic substitution reactions. Additionally, it acts as a building block for the synthesis of amino acids, peptides, and other complex organic compounds.
Application
- Measuring antioxidant capacity using the ORAC and TOSC assays.: This study details the use of α-Keto-γ-(methylthio)butyric acid sodium salt in assessing antioxidant capacity through ORAC and TOSC assays, emphasizing its utility in metabolic and chemical synthesis research (Garrett AR et al., 2010).

D-Methionine was converted to L-methionine in a reaction system where four enzymes were used. D-amino acid oxidase (D-AAO) from Arthrobacter protophormiae was used for the complete conversion of D-methionine to 2-oxo-4-methylthiobutyric acid. Catalase was added to prevent 2-oxo-4-methylthiobutyric acid decarboxylation.

The present study investigated the proposed involvement of contaminant-stimulated reactive oxygen species (ROS) production in disease processes in fish. NAD(P)H-dependent ROS production of subcellular fractions was determined by the iron/EDTA-mediated oxidation of 2-keto-4-methiolbutyric acid.
