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).

Ion-trap detection of volatile organic compounds in alveolar breath.

M Phillips et al.

Clinical chemistry, 38(1), 60-65 (1992-01-01)

We describe a method for the collection and microanalysis of the volatile organic compounds in human breath. A transportable apparatus supplies subjects with purified air and samples their alveolar breath; the volatile organic compounds are captured in an adsorptive trap

A low-barrier hydrogen bond in the catalytic triad of serine proteases.

P A Frey et al.

Science (New York, N.Y.), 264(5167), 1927-1930 (1994-06-24)

Spectroscopic properties of chymotrypsin and model compounds indicate that a low-barrier hydrogen bond participates in the mechanism of serine protease action. A low-barrier hydrogen bond between N delta 1 of His57 and the beta-carboxyl group of Asp102 in chymotrypsin can

Electron spin-lattice relaxation in radicals containing two methyl groups, generated by gamma-irradiation of polycrystalline solids.

James R Harbridge et al.

Journal of magnetic resonance (San Diego, Calif. : 1997), 159(2), 195-206 (2002-12-17)

The effects of methyl rotation on electron spin-lattice relaxation times were examined by pulsed electron paramagnetic resonance for the major radicals in gamma-irradiated polycrystalline alpha-amino isobutyric acid, dimethyl-malonic acid, and L-valine. The dominant radical is the same in irradiated dimethyl-malonic

Application of capillary electrophoresis with laser-induced fluorescence detection for routine determination of methylmalonic acid in human serum.

J Schneede et al.

Analytical chemistry, 67(5), 812-819 (1995-03-01)

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)

Anaerobic mineralization of quaternary carbon atoms: isolation of denitrifying bacteria on dimethylmalonate.

O Kniemeyer et al.

Applied and environmental microbiology, 65(8), 3319-3324 (1999-07-31)

The microbial capacity to degrade simple organic compounds with quaternary carbon atoms was demonstrated by enrichment and isolation of five denitrifying strains on dimethylmalonate as the sole electron donor and carbon source. Quantitative growth experiments showed a complete mineralization of
