ChemInform Abstract: The Vibrational Spectra and Structure of Oxaloacetic Acid.

Chemischer Informationsdienst, 1986
Abstract The complete vibrational spectra of oxaloacetic acid have been recorded. Infrared spectra were collected at liquid N 2 as well as ambient temperature, while the Raman data were collected at ambient temperature only. A vibrational assignment is proposed based on an enol structure in the solid phase.

Oxaloacetic acid tautomeric and hydrated forms in solution

Biochemical and Biophysical Research Communications, 1972
Summary The proportions of keto-, enol- and hydrated forms of oxaloacetate in solution have been investigated in stopped-flow studies with malate dehydrogenase. At pH 7.4, 74.3% is keto-oxaloacetate, 17.8% is enol-oxaloacetate and 7.8% 2, 2-dihydroxysuccinate (the hydrated gem -diol).

Metal-ion catalyzed decarboxylation of oxaloacetic acid

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1973
Decarboxylation of oxaloacetic acid is accelerated by hydrated metal ions. The thermodynamic data of activation ΔG[graphic omitted], ΔH[graphic omitted] and ΔS[graphic omitted] for the rate-determining process were determined. The main species involved in autodecarboxylation was identified as univalent hydrogen oxaloacetate anion.

Synthesis, storage, and stability of [4-14C]oxaloacetic acid

Analytical Biochemistry, 1985
A simple procedure for preparing [4-14C]oxaloacetic acid based on the reaction between [14C]HCO-3 and phosphoenolpyruvate catalyzed by phosphoenolpyruvate carboxylase is described. A simple method for preparing highly purified phosphoenolpyruvate carboxylase from maize leaves is described and the degradation of oxaloacetate under conditions of varying ...

Effect of Ammonium Salts on the Decarboxylation of Oxaloacetic Acid in Atmospheric Particles

ACS Earth and Space Chemistry, 2021
Oxaloacetic acid (OAA) is a 3-oxocarboxylic acid formed from the oxidation of succinic acid. OAA and other 3-oxocarboxylic acids experience a decarboxylation reaction in aqueous solutions, which ca...
