  2. 1. Characterization of dissolved organic matter : An analytical challenge

    Author : Claudia Patriarca; Jonas Bergquist; Lars Tranvik; Jeffrey A. Hawkes; Jonathan Martin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Dissolved organic matter (DOM) is the prevalent form of organic carbon in most aquatic environments. It is an ultra-complex mixture that plays a crucial role in global carbon cycling. Despite its importance it is still poorly understood due to its extreme heterogeneity and intricacy. READ MORE

  4. 2. Characterisation of starch: development of analytical methods

    Author : Gunilla Nilsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; substitution pattern; microdialysis; HPAEC-PAD; NMR; biosensor; IMER; potato amylopectin starch; amylose; amylopectin; chain length; Analytical chemistry; Analytisk kemi;

    Abstract : Starch, comprised of amylose and amylopectin, is a very complex biopolymer. Different methods are therefore needed for the investigation of the molecular structures of amylose and amylopectin. In this thesis analytical methods have been developed and various techniques were combined for the characterisation of starch. READ MORE

  5. 3. Strategies to explore the membrane proteome of a cell

    Author : Gianluca Maddalo; Leopold L. Ilag; Peter James; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. READ MORE

  6. 4. Analysis of Metabolites in Complex Biological Samples Using LC/MS and Multivariate Data Analysis : Metabolic Fingerprinting and Detection of Biomarkers

    Author : Helena Idborg; Sven Jacobsson; Per-Olof Edlund; Jonas Bergquist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolomics; Metabonomics; Metabolic Fingerprinting; Drug Metabolism; Biomarkers; Human Plasma; Rat Urine; LC MS; ZIC-HILIC; UPLC; UHPLC; ToF; Curve Resolution; Peak Detection; Pattern Recognition; Classification; PCA; PLS; PARAFAC; N-PLS; Data Fusion; Hierarchical Modeling; Batch modeling; Data Concatenation; Breast Cancer; Phospholipidosis; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : To facilitate early diagnosis of diseases and elucidation of the processes involved in their development and progression, various specific compounds or ‘biomarkers’ are often monitored. The first step is to decide which compounds to analyze. READ MORE

  7. 5. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    Author : Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Abstract : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. READ MORE
