This study examined the metabolism of dihomo-gamma-linolenic acid (20:3(n-6] in casein-elicited murine peritoneal macrophages. Cells were incubated with [14C]20:3(n-6) in the presence of 1% fetal bovine serum (FBS) or 0.025% bovine serum albumin (BSA), and the distribution and identity of membrane-bound and soluble products were determined. Approx.

Conversion of 8,11,14-eicosatrienoic acid to 11,12-epoxy-10-hydroxy-8-heptadecenoic acid by aorta
Prostaglandins, 1983Particulate fractions from fetal calf aorta convert 8,11,14-eicosatrienoic acid to a number of products derived from 12-hydroperoxy-8,10-heptadecadienoic acid, including 2 stereoisomers of 11,12-epoxy-10-hydroxy-8-heptadecenoic acid (11,12e-10h-17:1), which were identified by mass spectrometry.

The enzymic conversion of all‐cis 8,11,14‐eicosatrienoic acid into prostaglandin E1
Recueil des Travaux Chimiques des Pays-Bas, 1966AbstractIn the biosynthesis of prostaglandin E1 (PGE1) with an enzyme fraction of sheep vesicular glands glutathione and a moderate amount of antioxidant are required to obtain maximum yield; two oxygen molecules are consumed per mole PGE1 formed. By altering the incubation conditions, besides PGE1 various other products can be obtained.A scheme for ...

The effect of ticlopidine after oral administration was determined on the aggregation of rat blood platelets and on the formation of cyclo-oxygenase, and lipoxygenase metabolites from arachidonic acid (AA) and 8,11,14-eicosatrienoic acid in rat platelets and in the kidney. 1. Platelet aggregation is inhibited by ticlopidine.

AbstractMethyl‐branched derivatives of methyl 8,11,14‐eicosatrienoate form stable liquid‐expanded monolayers. Surface areas are expanded by the methyl branch. The expansion effect is a function of surface pressure. At high surface pressure, the greatest expansion occurs with a mid‐point methyl branch.

On the Incorporation of Oxygen in the Conversion of 8,11,14-Eicosatrienoic Acid to Prostaglandin E1
Journal of the American Chemical Society, 1965Prostaglandin E1 was synthesized by incubating 81114-eicosatrienoic acid with a proportion of vesicular gland for 10 minutes in an atmosphere of labeled oxygen. To determine the origin of the oxygens of the ring a derivative was oxidized by permanganate-periodate and analyzed by mass spectrometry.
