Gas-liquid chromatography of 2-chloroethyl esters using a detector specific for halogens

open access: yesJournal of Lipid Research, 1967
The gas-liquid chromatography of 2-chloroethyl derivatives of short- and long-chain monocarboxylic acids, and of short-chain dicarboxylic acids and aldehydes has been studied with a dual-flame ionization detector that provided simultaneous records of the

Solid state and sub-cooled liquid vapour pressures of cyclic aliphatic dicarboxylic acids [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
Knudsen Effusion Mass Spectrometry (KEMS) has been used to measure for the first time the solid state vapour pressures of a series of aliphatic cyclic dicarboxylic acids with increasing ring size. Additionally the atmospherically important compounds; <

Abnormal urinary excretion of unsaturated dicarboxylic acids in patients with medium-chain acyl-CoA dehydrogenase deficiency.

open access: yesJournal of Lipid Research, 1990
Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency is the most frequently described metabolic disorder of fatty acid oxidation in humans. Acute episodes are usually characterized biochemically by the appearance of nonketotic dicarboxylic aciduria.

cis-Cyclohexane-1,4-dicarboxylic acid [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
In the title compound, C8H12O4, the two carboxyl groups are on the same side of the cyclohexane ring and the ring adopts a chair conformation. Adjacent molecules related by an inversion centre are linked by pairs of O—H...O hydrogen bonds, forming a zigzag chain along [1\overline{1}\overline{1}].

High abundances of dicarboxylic acids, oxocarboxylic acids, and alpha-dicarbonyls in fine aerosols (PM2.5) in Chengdu, China during wintertime haze pollution [PDF]

open access: yes, 2015
Daytime and nighttime fine aerosol (PM2.5) samples were collected during a haze episode in January 2013 within the urban area of Chengdu, southwest China. Aerosol samples were analyzed for low-molecular-weight homologous dicarboxylic acids, oxocarboxylic

RB-TnSeq elucidates dicarboxylic-acid-specific catabolism in β-proteobacteria for improved plastic monomer upcycling

open access: yesApplied and Environmental Microbiology
Dicarboxylic acids are key components of many polymers and plastics, making them a target for both engineered microbial degradation and sustainable bioproduction. In this study, we generated a comprehensive data set of functional evidence for the genetic
