  2. 21. Pheromone production in the butterfly Pieris napi L

    Author : Rushana Murtazina; Raimondas Mozuraitis; Joop van Loon; KTH; []
    Keywords : Pieris; Lepidoptera; pheromone; aphrodisiaca; antiaphrodisiaca; biosynthesis; flower volatiles; stable isotopes; incorporation; neral; geranial; methyl salicylate; benzyl cyanide; L - phenylalanine;

    Abstract : Aphrodisiac and anti-aphrodisiac pheromone production and composition in the green-veined white butterfly Pieris napi L. were investigated.Aphrodisiac pheromone biosynthesis had different time constraints in butterflies from the diapausing and directly developing generations.

  4. 22. Heparan Sulfate and Development : A Study of NDST Deficient Mice and Embryonic Stem Cells

    Author : Katarina Holmborn; Lena Kjellén; Erik Forsberg; Catherine L. Merry; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell and molecular biology; heparan sulfate; proteoglycan; biosynthesis; N-deacetylase N-sulfotransferase; NDST; gene targeting; embryonic development; lung development; mast cells; Cell- och molekylärbiologi;

    Abstract : Heparan sulfate (HS) proteoglycans consist of sulfated HS chains covalently bound to core proteins. They are ubiquitously expressed, on the cell surface and in the extracellular matrix, throughout the body. READ MORE

  5. 23. Naphthoxylosides Investigations into glycosaminoglycan biosynthesis

    Author : Mårten Jacobsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; proteoglycan; Organic chemistry; nucleophilic aromatic substitution; thioether; glycosaminoglycan; xylosides; naphthoxylosides;

    Abstract : Glycosaminoglycans (GAGs) are members of a family of polysaccharide structures consisting mostly of repeating disaccharide units. Most GAGs are attached to specific serine residues in proteins to form proteoglycans (PGs). READ MORE

  6. 24. Aspects on dermatan sulfate metabolism

    Author : Erik Eklund; Matrixbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; Clinical biology; iduronic acid; galactosaminoglycan; Dermatan sulfate; biosynthesis;

    Abstract : The functions of proteoglycans often depend on the fine structure of the covalently attached glycosaminoglycan (GAG) side-chains. The process leading to the mature GAG is complex and involves a multitude of different enzymatic steps. READ MORE

  7. 25. Enzymes involved in heparan sulfate chain elongation : Function of a novel family of tumor suppressors?

    Author : Thomas Lind; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; biosynthesis; glycosyltransferase; EXT1; EXT2; UDP-glucosedehydrogenase; KfiC; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Abstract : Heparan sulfate (HS) is a glycosaminoglycan associated with many physiological functions such as regulation of growth factor action and cell adhesion. The HS polysaccharide is synthesized by alternating addition of D-glucuronic acid (GlcA) and N-acetyl-D-glucosamine (GlcNAc) units from the corresponding UDP-sugar precursors. READ MORE
