  1. 1. Lipid Composition and Deterioration in Light and Dark Muscle of Rainbow Trout (Oncorhynchus mykiss)

    Författare :Torbjörn Ingemansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Docosahexaenoic acid; lipid classes; fatty acids; muscle lipids; Palmitic acid; trout; differences; lipids; fish;

    Sammanfattning : Nutritionally valuable lipids, including lipid classes and their fatty acids in light and dark muscle, have been determined and analyzed in farmed rainbow trout. Dark muscle was found to have a higher content of total lipids than light muscle, 7.3 wt% versus 3.0 wt%, which was mostly accounted for by neutral lipids, especially triacylglycerols. LÄS MER

  3. 2. Systems Biology of Yeast Lipid Metabolism

    Författare :Pramote Chumnanpuen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transcriptome; Integrated analysis; Lipidome.; Inositol-choline; Opi1; Yeast lipid metabolism; high throughput techniques; Ino4; TORC1; Snf1; Ino2;

    Sammanfattning : Lipid metabolism plays an important role in the development of many different life-style related diseases, such as type 2 diabetes and atherosclerosis, and understanding the molecular mechanisms behind regulation of lipid biosynthesis and degradation may lead to development of new therapies. In this project we undertook a global study of lipid metabolism in the eukaryotic model organism Saccharomyces cerevisiae. LÄS MER

  4. 3. Development of Methods for Determination of Fat and Trace Constituents in Food, with Emphasis on Supercritical Fluid Extraction

    Författare :Hans Berg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supercritical fluid extraction; Steroids; SFE; Sample preparation; Meat; Lipid classes; Food; Fatty acid composition; Fat content; 3-butanediol; 2; Diacetyl; Acetoin; Androstenone; vitamins A and E.; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Sample preparation is the most time-consuming step in an analysis. Traditional sample preparation techniques consume large amounts of organic solvents, are time-consuming and are difficult to automate. LÄS MER

  5. 4. Essentially Lipids : Analytical methods for the characterization of lipid materials

    Författare :Petter Olsson; Bengt Herslöf; Jan Holmbäck; Torgny Fornstedt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; Chromatography; HPLC; Charged Aerosol Detection; Evaporative light scattering detection; mass spectrometry; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis describes analytical methods for chromatographic characterizations of lipids in biological and technical systems.Lipids are a group of compounds with a central role in all known forms of life. In addition to the biological roles, lipids are also components in many products of our daily usage. LÄS MER

  7. 5. NMR metabolomics and lipid analyses in salmonid tissue : response to alternative feeds

    Författare :Liane Wagner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Salmonids are fatty fish and contain high amounts of omega-3 polyunsaturated fatty acids, beneficial in human nutrition. However, the aquaculture industry has expanded greatly in recent decades, increasing demand for fishmeal (FM) and fish oil (FO) for fish feed, while the supply of fish raw materials has remained static or declined.
