Dicarboxylic acids as markers of fatty acid peroxidation in diabetes

Atherosclerosis, 2000
Increased urinary excretion of dicarboxylic acids (DAs) has been well known in patients with diabetic ketoacidosis (DKA). It was known that small amounts of such DAs were also detected in urine from healthy humans. Upon chemical, radiation-induced or enzymatic oxidation, cis-polyunsaturated fatty acids (PUFA) have previously been shown to generate ...

Urinary dicarboxylic acids in Reye syndrome

The Journal of Pediatrics, 1985
Urine from 12 patients with Reye syndrome was examined by gas-liquid chromatography for identification of organic acids. Large amounts of lactic acid, dicarboxylic acids (adipic, suberic, and sebacic), and 3-OH butyric acid were noted. The mean (+/- SD) total dicarboxylic acid concentration was 0.98 +/- 0.24 mg/mg creatinine, compared with 0.006 +/- 0 ...

Compartmentation of dicarboxylic acid β-oxidation in rat liver: importance of peroxisomes in the metabolism of dicarboxylic acids

Biochimica et Biophysica Acta (BBA) - General Subjects, 1989
Peroxisomal and mitochondrial beta-oxidation of dicarboxylic acids (DCAs) were investigated and compared. When isolated hepatocytes were incubated with DCAs of various chain lengths, H2O2 was derived from peroxisomal beta-oxidation, the rates of its generation being comparable to those seen with monocarboxylic acids (MCAs), whereas the rates of ketone ...

Conformations, energies, and intramolecular hydrogen bonds in dicarboxylic acids: Implications for the design of synthetic dicarboxylic acid receptors

Journal of Computational Chemistry, 2005
AbstractThe various conformers of the dicarboxylic acids HO2C(CH2)nCO2H, n = 1–4, were obtained using density functional methods (DFT), both in the gas phase and in the aqueous phase using a polarized continuum model (PCM). Several new conformers were identified, particularly for the two larger molecules glutaric (n = 3) and adipic acid (n =4).

5,8-Dimethoxynaphthalene-1,6-dicarboxylic Acid

Acta Crystallographica Section C Crystal Structure Communications, 1997
The title compound, C14H12O6, crystallized in the centrosymmetric space group Pbca but does not exhibit hydrogen bonding of the usual cyclic dimer type about a center of symmetry or otherwise. Each molecule is linked to six neighbors by eight hydrogen bonds, which leads, in this structure, to a rich pattern of chains.

[46] Acylation with dicarboxylic acid anhydrides

1972
Publisher Summary This chapter discusses acylation with dicarboxylic acid anhydrides. Succinic and maleic anhydride, or analogs of these two compounds, is utilized in a variety of protein modification studies. During the course of the reaction most of the anhydride is hydrolyzed.

THE SYNTHESIS OF OPSOPYRROLE-DICARBOXYLIC ACID

Canadian Journal of Chemistry, 1955
The methyl groups of the pyrroles Ia and IIa react with sulphuryl chloride to give dichloromethyl derivatives which hydrolyze to aldehydes. The pyrrole Ia also forms a trichloromethyl derivative which hydrolyzes to the corresponding acid. Alkaline decarboxylation of the latter gives opsopyrrole-dicarboxylic acid, IVa.
