Biochem/physiol Actions

Arachidonic acid (AA) is an unsaturated omega-6 fatty acid constituent of the phospholipids of cell membranes. Phospholipase A2 releases AA from the membrane phospholipids in response to inflammation. AA is subsequently metabolized to prostaglandins and thromboxanes by at least two cyclooxygenase (COX) isoforms, to leukotrienes and lipoxins by lipoxygenases, and to epoxyeicosatrienoic acids via p450-catalyzed metabolism. AA and its metabolites play important roles in a variety of biological processes, including signal transduction, contraction, chemotaxis, and cell proliferation, differentiation and apoptosis. AA has been demonstrated to bind to the α subunit of G protein and inhibit the activity of Ras GTPase-activating proteins (GAPs). Cellular uptake of AA is energy dependent and involves protein-facilitated transport across the plasma membrane.

Biomarkers of fetal exposure to alcohol are important to establish so that early detection and intervention can be made on these infants to prevent undesirable outcomes. The aim of this study was to analyze long-chain fatty acid ethyl esters (FAEEs)

Alcohol (Fayetteville, N.Y.), 83, 29-35 (2019-06-09)
Problems of stability were found for biomarkers of alcohol consumption: ethyl glucuronide (EtG), ethyl sulfate (EtS), phosphatidylethanols (PEths), and fatty acid ethyl esters (FAEEs) in whole blood. The purpose of this study was to establish a method for the determination

Purified rat pancreas protein kinase C (PKC) is activated by unsaturated free fatty acids (oleic and arachidonic). The ethyl esters of these fatty acids are ineffective as enzyme activators. However, when the ethyl esters are added in combination with a

Two polyunsaturated fatty acids (PUFAs) or their esters were mixed, and their oxidation processes were measured at 65 degrees C and ca. 0% relative humidity. Except when a PUFA ester was mixed with a free PUFA, the oxidation of the

Fatty acid ethyl esters (FAEEs) are nonoxidative ethanol metabolites that have been implicated as mediators of alcohol-induced organ damage. FAEEs are detectable in the blood after ethanol ingestion, and on that basis have been proposed as markers of ethanol intake.
