Hydrophobic interactions in the stability of porphyrin-containing proteins
(Society of Physical Chemists of Serbia, 2008)
This study aims to systematically characterize hydrophobic interactions of porphyrins in porphyrin containing proteins. Structures of porphyrin containing proteins from the Protein Data Bank (PDB) Select January 2007, the ...
Hydrogen bonds and XH/pi interactions of porphyrins in proteins
(Belgrade, Serbia : Faculty of Chemistry, University of BelgradeGermany : Alexander von Humboldt Foundation, 2007)
Structures of porphyrin containing proteins from the Protein Data Bank (PDB) Select January 2007, the list of non-redundant protein chains (25% threshold), were searched in order to find out hydrogen bonds and XH/pi ...
Physicochemical Characterization of Carrageenans - A Critical Reinvestigation
(Wiley, 2008)
Kappa-, iota-, and lambda-carrageenan
(food grade) were analyzed by static light scattering
(MALS in batch mode) in 0.1M NaNO3 at 25 and 60 C,
earlier heated up to 90 C or not. At 25 C, there was a
strong tendency ...
Cholesterol bound to hemoglobin in normal human erythrocytes
(Turkish Biochemical Society, 2003)
Our results demonstrate that in contrast to Ch and PL contents of RBC membrane which are confined to a narrow range, the lipid levels estimated in intact RBCs showed more variation: the lowest individual values for RBC ...
Insulin-activated gpi-transamidase in human erythrocytes
(Turkish Biochemical Society, 2003)
Our results demonstrate that exposure of erythrocyte membranes to insulin cause the activation of membrane protease, as well as that the formation of GPI-Hb parallels its activity. This, together with recent findings ...
Syntheses of Tetrahydro-β-Carbolines via Tandem Hydformylation / Pictet-Spengler Reaction, Scope and limitations
(Royal Society of Chemistry, 2008)
A novel one-pot synthesis of tetrahydro-β-carboline systems via tandem hydroformylation–Pictet–Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient ...
Dismutacija NO u NO+ i NO- vrste katalizovana jonima gvožđa u prisustvu mokraćne kiseline
(Belgrade : Serbian Chemical Society, 2001)
U našim ranijim radovima utvrdili smo da pri izlaganju cerebrospinalne tečnosti (CSF) azot monoksidu in vitro dolazi do njegove dismutacije u NO+ i NO' vrste. CSF sadrži tzv "slobodno" gvoždje u mikromoiarnim koncentracijama ...
Electrostatic Study of the Proton Pumping Mechanism in Bovine Heart Cytochrome c Oxidase
(American Chemical Society (ACS), 2004)
Cytochrome c oxidase (CcO) is the terminal enzyme of the cell respiratory chain in mitochondria and aerobic bacteria. It catalyzes the reduction of oxygen to water and utilizes the free energy of the reduction reaction for ...
Hyperbranched Polymers Based on Aliphatic Polyesters – Synthesis and Characterization
(Saarbrücken, Deutschland : VDM Verlag Dr. Müller Aktiengesellschaft & Co. KG, 2008)
Two series of hydroxy-functional hyperbranched polymers based on aliphatic polyesters have
been prepared from the 2,2-bis(hydroxymethyl)propionic acid (AB2 monomer) and the ditrimethylolpropane
(B4 functional core). A ...
Poly(methacrylamide)/poly(itaconic acid) complexes
(The Society of Physical Chemists of Serbia, 2002)
Polymerization in a system containing template (linear macromolecule) which interacts with the growing polymer (a "daughter polymer") and influence its structure is called template polymerization. The ordering in the growing ...
