    Sammanfattning : Epoxy fatty acids are useful molecules and find a number of applications e.g. as PVC plasticisers and stabilisers, additives in polyurethane production, reactive diluents in paints, corrosion protection agents, etc. LÄS MER

  2. 2. Mass Spectrometric Analysis of Oxylipins Application to Cytochrome P450-Dependent Metabolism

    Sammanfattning : Cytochrome P450 (CYP) family 4 constitutes monoxygenases responsible for hydroxylation of fatty acids and other lipids. For example, CYP4F3 metabolizes leukotrienes and CYP4F8 prostaglandin H. Importantly, six of the twelve CYP4 enzymes are orphans, i.e. LÄS MER

  3. 3. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

    Sammanfattning : Popular Abstract in Swedish För över 100 år sedan upptäckte den franske naturalisten Jean-Henri Fabre att en nattfjärilshona som han hade på sitt skrivbord lyckades attrahera åtskilliga hanar, trots att honan var gömd bakom ett skynke och hannarna således inte kunde se henne. Fabre gissade att det var någon för honom okänd doft som låg bakom mysteriet. LÄS MER

  4. 4. Free fatty acids and insulin hypersecretion studied in human islets

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jing Cen; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; free fatty acids; palmitate; human islets; EndoC-βH1 cells; metformin; sorcin; insulin secretion; mitochondrial respiration; ER stress; human transcriptome array; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Free fatty acid (FFA) levels are increased in many obese subjects. High FFA levels stimulate the pancreatic beta-cells but have negative long-term effects. In obese children with high FFA levels circulating insulin concentration is high early in life but decline with age precipitating the development of type 2 diabetes mellitus (T2DM). LÄS MER

  5. 5. Analysis of halogenated fatty acids in fish lipids by gas chromatography with electrolytic conductivity detection and mass spectrometry

    Detta är en avhandling från Analytical Chemistry, Lund University

    Författare :Huiling Mu; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism.; identification; methanolysis; enzymatic hydrolysis; chlorinated fatty acids; organohalogen compounds; mass spectrometry; Gas chromatography; electrolytic conductivity detection; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Organochlorine compounds in fish lipids were characterized by studying the partitioning of chlorinated species into acidic and neutral fractions before and after hydrolysis of the lipids, and after transesterification to fatty acid methyl esters (FAMEs). Chlorinated fatty acids (Cl-FAs) were found to be the major organochlorine components in the fish lipids. LÄS MER
