The Unsaturated Fatty Acids of Egg Lecithin
The work on liver lecithins by Levene and Ingvaldsen’ and by Levene and Simms,z has shown the existence of lecithins which are distinguished from one another by the nature of their unsaturated fatty acids. There were isolated from liver lecithin, two unsaturated fatty acids, oleic and arachidonic, as well as two saturated acids, palmitic and stearic. Hence on the basis of the present findings i...
متن کاملPositional asymmetry of fatty acids on lecithin.
The possibility that naturally occurring lecithins may contain 1 molecule each of a saturated and an unsaturated fatty acid has never been shown. The data of Levene and Rolf (1) on the brominated lecithins from liver could be interpreted as indirect support for this theory. However, the evidence provided by Contardi and Latzer (2), Snider and Bloor (3), and Sinclair (4) on the fatty acid compos...
متن کاملIsolation and determination methods for brain cerebrosides, hydroxy fatty acids, and unsaturated and saturated fatty acids *
A new method is described for the isolation of nearly pure total cerebrosides from fresh brain. Florisil columns are used to separate the cerebroside hydroxy and normal acids, in the form of their esters, and to separate the saturated and unsaturated esters of each group. The esters within each class are determined by gas chromatography, the hydroxy esters being run as the methyl ethers. Yields...
متن کاملCombined effect of unsaturated fatty acids and saturated fatty acids on the metabolic syndrome: tehran lipid and glucose study
AIMS The aim of this study was to investigate whether the background intakes of total dietary fat, monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) modulate the effects of dietary saturated fatty acids (SFA) on metabolic syndrome (MetS). MATERIAL AND METHODS This population-based cross-sectional study was conducted on a representative sample of 4,677 adults, aged 19 t...
متن کاملDifferential roles of unsaturated and saturated fatty acids on autophagy and apoptosis in hepatocytes.
Fatty acid-induced lipotoxicity plays a critical role in the pathogenesis of nonalcoholic liver disease. Saturated fatty acids and unsaturated fatty acids have differential effects on cell death and steatosis, but the mechanisms responsible for these differences are not known. Using cultured HepG2 cells and primary mouse hepatocytes, we found that unsaturated and saturated fatty acids different...
