1. 1. Chemo-Enzymatic Epoxidation of Unsaturated Fatty Acids

   Författare :Cecilia Orellana Coca Åkerman; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; solvent-free process.; Candida antarctica lipase B esterification; chemo-enzymatic epoxidation; Unsaturated fatty acids; epoxides;

   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

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

   Författare :Tomas Nilsson; Ernst Oliw; Johan Bylund; Mikael Hedeland; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epoxyalcohols; fatty acids; hydroperoxides; electrospray ionization; ichthyosis; CYP4; linear ion trap; fragmentation mechanism; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Biochemical Pharmacology; Biokemisk farmakologi;

   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

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

   Författare :Åsa Hagström; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

   Sammanfattning : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.

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

   Författare :Jing Cen; Peter Bergsten; Miriam Cnop; Uppsala universitet; []
   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

7. 5. Developing a food waste-based volatile fatty acids platform using an immersed membrane bioreactor

   Författare :Steven Wainaina; Jukka Rintala; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food waste; anaerobic digestion; volatile fatty acids; immersed membrane bioreactor; edible filamentous fungi; Resource Recovery; Resursåtervinning;

   Sammanfattning : Approximately 1.3 billion tons of food waste is produced globally every year. In principle, all the resources in the supply chain are lost (e.g. LÄS MER
