Enzymatic formation of hexadecenoic acid from palmitic acid.

Enzymatic Formation of Catechol from Anthranilic Acid.

Anthranilic acid is known to be formed from kynurenine in animals and microorganisms (3-6) and to be degraded by cell-free extracts of a Pseudomonas species adapted to L-tryptophan (7). Catechol has been postulated as an intermediate in the catabolism of anthranilic acid on the basis of experiments utilizing sequential enzyme induction (8). Several groups of investigators have recently succeede...

Evaluation of linoleic acid, eladic acid and palmitic acid for cytotoxicity and anti-inflammatory activities

Background and objectives: Nigella sativa seeds have shown to possess anti-inflammatory, anti-oxidant, trenquillizer, chemopreventive and anti-neoplastic effects. Besides, they areused as nutritional flavoring agents. We have investigated the protective effects of N.  sativa seeds hexane extract and active principles against methyl phenyl pyridine (MP...

Protective Effects of Linoleic Acid against the Cytotoxicity of Palmitic Fatty Acid in Rat Cardiomyocytes

Background & Aims: Lipotoxicity is the process through which accumulation of lipid intermadiates leads to cellular dysfunction. The worldwide prevalence of cardiovascular diseases has been increased dramatically due to lipotoxicity. According to the peformed studies, saturated and unsaturated fatty acids differ significantly in their contributions to lipotoxicity. It has been r...

The Biosynthesis of Folic Acid. Iii. Enzymatic Formation of Dihydrofolic Acid from Dihydropteroic Acid and of Tetrahydropteroylpolyglutamic Acid Compounds from Tetrahydrofolic Acid.

Although dihydrofolic acid can be formed enzymatically, in the presence of adenosine triphosphate, from 2-amino4-hydroxy-6hydroxymethyldihydropteridine and p-aminobenzoylglutamic acid (3, 4), Brown, Weisman, and Molnar (4) have postulated that dihydropteroic acid, instead of p-aminobenzoylglutamic acid, is the normal intermediate in dihydrofolate synthesis in Escherichia coli. They have present...
