Ozonized Unsaturated Triglycerides as Precursors of Urinary Dicarboxylic Acids

چکیده
Oral administration of ozonized sunflower oil to Wistar rats has produced changes in the urinary content of dicarboxylic acids. Heptanedioic acid (Pimelic acid) and nonanedioic acid (Azelaic acid) were the major increased dicarboxylic acids founded. The aim of this work is the study of the urinary dicarboxylic acid profiles of Wistar rats, orally treated with ozonized standard triglycerides. The dicarboxylic acids were extracted and derivatized before the analysis by Gas Chromatography Mass Spectrometry. The urinary dicarboxylic acid profiles of the rats that received ozonized triolein, only showed the increasing of heptanedioic and nonanedioic acids. However, when ozonized trilinolein was applied, the profile is similar to that obtained, when ozonized sunflower oil was administered. A biochemical mechanism to explain the formation of dicarboxylic acids from ozonated unsaturated triglycerides was proposed.

Abnormal urinary excretion of unsaturated dicarboxylic acids in patients with medium-chain acyl-CoA dehydrogenase deficiency.
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. In addition, other abnormal metabolites, such as suberylglycine, n-hexanoylglycine, 3-phenylpropionylglycine, and octanoylcarnitine, are excreted ...

The mitochondrial beta-oxidation system is one of the central metabolic pathways of energy metabolism in mammals. Enzyme defects in this pathway cause fatty acid oxidation disorders. To elucidate the role of 2,4-dienoyl-CoA reductase (DECR) as an auxiliary enzyme in the mitochondrial beta-oxidation of unsaturated fatty acids, we created a DECR-deficient mouse line. In Decr(-/-) mice, the mitoch...
متن کاملIdentification of isomeric unsaturated medium-chain dicarboxylic acids in human urine.
Dicarboxylic aciduria caused by enhanced or inhibited fatty acid metabolism is usually described as increased urinary excretion of saturated medium-chain dicarboxylic acids, such as adipic, suberic, and sebacic acids. Besides these saturated acids, increased excretion of unsaturated dicarboxylic acids is also observed. However, the structural identities of these unsaturated dicarboxylic acids a...
متن کاملSingle-Step Access to Long-Chain α,ω-Dicarboxylic Acids by Isomerizing Hydroxycarbonylation of Unsaturated Fatty Acids
Dicarboxylic acids are compounds of high value, but to date long-chain α,ω-dicarboxylic acids have been difficult to access in a direct way. Unsaturated fatty acids are ideal starting materials with their molecular structure of long methylene sequences and a carboxylate functionality, in addition to a double bond that offers itself for functionalization. Within this paper, we established a dire...

Ozonized oils represent an interesting pharmaceutical approach to the management of a variety of dermatological pathologies. Ozone reacts with carbon-carbon double bonds of unsaturated fatty acids according to the mechanism described by Criegee, forming ozonides or 1,2,4 trioxolane rings and peroxides as the most important products, responsible for the antimicrobial activity and stimulating tis...
