  1. 1. Synthesis of aromatic bis- and tris(amino acids) and chiral dendrimers

    Detta är en avhandling från Department of Organic Chemistry, Lund University

    Författare :Andreas Ritzén; Lunds universitet.; Lund University.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; HWE reaction; asymmetric hydrogenation; Heck reaction; Amino acids; chiral dendrimers;

    Sammanfattning : A number of protected aromatic bis- and tris(amino acids) have been synthesised by catalytic asymmetric hydrogenation of the corresponding didehydroamino acid derivatives. The didehydroamino acid derivatives were prepared either by a Heck coupling of a 2-amidoacrylate with an aryl dihalide, or by Horner-Wadsworth-Emmons olefination of aromatic aldehydes with phosphonylglycine reagents.

  2. 2. Synthesis of glycosylated amino acids. Solid-phase assembly of T-cell immunogenic glycopeptides and fragments from HIV gp120

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Mikael Elofsson; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HIV; immunogenic glycopeptides; T-cell; MHC; solid-phase glycopeptide synthesis; glycopeptides; glycoside synthesis; glycosylated amino acids; gp120; neoglycosphingolipids; Organic chemistry; Organisk kemi;

    Sammanfattning : Synthetic glycopeptides are valuable tools for studies of the biological functions of protein-bound carbohydrates. Today glycopeptides are efficiently prepared by solid-phase synthesis according to the 9-fluorenylmethoxycarbonyl (Fmoc) protocol, provided that suitable glycosylated amino acids are available.

  3. 3. Macrocyclic Carbohydrate/Amino Acid Hybrid Molecules - Synthesis and Evaluation as Artificial Receptors

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Johan Billing; Lunds universitet.; Lund University.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3-dipolar cycloaddition; 3-triazoles; 2; 1; molecular recognition; artificial receptors; sugar amino acids; cyclic peptides; macrocycles; Organic chemistry; Organisk kemi;

    Sammanfattning : Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. LÄS MER

  4. 4. Microdialysis sampling from skeletal muscle and adipose tissue with special reference to the effects of insulin on tissue blood flow and glucose metabolism

    Detta är en avhandling från Stockholm : Norstedts Tryckeri AB

    Författare :Hans Rosdahl; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; microdialysis; insulin; skeletal muscle; adipose tissue; glucose; amino acids; Key words: microdialysis; human; skeletal muscle; adipose tissue; ethanol; insulin; glucose; lactate; glycerol; urea; amino acids; adrenaline; isoprenaline; adenosine; vasopressin; microcirculation; dextran; colloid osmotic pressure; isometric exercise;

    Sammanfattning : The general aim of the present thesis was to explore the possibility of using rnicrodialysis in vivo, for studies of the effects of insulin on glucose metabolism and blood flow in skeletal muscle and adipose tissue. With microdialysis sampling, a probe is perfused with a physiological solution. LÄS MER

  5. 5. Impact of root and mycorrhizal exudation on soil carbon fluxes : influence of elevated CO2 and metals

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Emma M. Johansson; Örebro universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; amino acids; 13C; carbon cycle; ectomycorrhiza; elevated CO2; exudation; DOC; LMWOA; metal stress; monosaccharides; oxalate; Pinus sylvestris; saprotrophic fungi; soil respiration; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied.
