应用


  • 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).

其他说明

Chemical Shift: 1.3 - 1.4 ppm (chemical shifts may slightly vary depending on the experimental conditions)
suitable NMR solvents: MeOD, D2O, DMSO-d6

Methylmalonic acid (MMA) in serum is an established marker of cobalamin deficiency. MMA and other short-chain dicarboxylic acids react with 1-pyrenyldiazomethane to form stable, highly fluorescent 1-pyrenylmethyl monoesters. We have analyzed these esters in human blood by capillary electrophoresis (CE)
