Application


  • Metabolic enzyme research: A study involving ECHDC1 knockout mice, which affect metabolism of branched-chain fatty acids, referenced the role of derivatives like dimethylmalonic acid in understanding metabolic disorders. This research is significant for biochemical studies related to metabolism and enzyme function (Dewulf et al., 2021).

  • NMR-based metabolomics: Utilizing NMR techniques, researchers have analyzed metabolites in biological samples, demonstrating the utility of dimethylmalonic acid in enhancing the resolution of metabolic profiling. This methodology is valuable in biochemical research, especially in studying complex biological matrices (Tang & Hatzakis, 2020).

Autres remarques
