  4. 2. Organic Phosphorus Compounds in Aquatic Sediments : Towards Molecular Identification with Mass Spectrometry

    Author : Heidi De Brabandere; Monica Waldebäck; Emil Rydin; Per J. R. Sjöberg; Rolf Danielsson; William T. Cooper; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrospray ionisation; mass spectrometry; liquid chromatography; organic phosphorus; aquatic sediment; eutrophication; sample preparation; extraction; Analytical chemistry; Analytisk kemi;

    Abstract : Phosphorus (P) regulates trophic status in most aquatic systems. However, only bioavailable P contributes to primary production. In most lakes and shallow seas, mineralisation of sediment P into its bioavailable form and its release to the water column is important for maintaining primary production. READ MORE

  5. 3. Analysis of Complex Biological Samples using Liquid Chromatography-Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

    Author : Margareta Ramström; Jonas Bergquist; Per Håkansson; Karin Markides; Carol Robinson; Uppsala universitet; []

    Abstract : Advances in science and technology during the past decade have greatly enhanced the level of the structural investigation of macromolecules – peptides and proteins. Biological mass spectrometry has become one of the most precise and sensitive techniques in peptide and protein analysis. READ MORE

  7. 5. Electrospray Ionization Mass Spectrometry for Determination of Noncovalent Interactions in Drug Discovery

    Author : Kurt Benkestock; Johan Roeraade; Renato Zenobi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; electrospray ionization; drug discovery; noncovalent interaction; complexes; human serum albumin HSA ; fatty acid binding protein FABP ; ribonuclease; ligand screening; Analytical chemistry; Analytisk kemi;

    Abstract : Noncovalent interactions are involved in many biological processes in which biomolecules bind specifically and reversibly to a partner. Often, proteins do not have a biological activity without the presence of a partner, a ligand. READ MORE
