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).
