    Abstract : Atherosclerosis is the leading cause of death and disability in the western world. Its clinical complications include acute myocardial infarction, sudden death and stroke. Thirty to 40 % of all ischemic strokes are caused by a carotid stenosis. READ MORE

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

    University dissertation from Lund University, Dept. of Biology

    Author : Åsa Hagström; Lund University.; Lunds universitet.; [2013]
    Keywords : 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;

    Abstract : 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.
