show by femtosecond mid-infrared spectroscopy that the water molecules enter the apolar matrix in the form of particularly hydrogen-bonded complexes with acetone. The OH stretching vibrations of the water molecule have been excited by an infrared laser pulse. Because the OH vibrations of the water ...
The ligand-docking behavior of hevein, the major latex protein from the rubber treeHevea brasiliensis(Euphorbiaceae), has been investigated by the unguided molecular dynamics (MD) simulation method. An oligosaccharide molecule, initially placed in an arbitrary position, was allowed to move around hevein...
Question: The first picture of DNA, as a result of X-ray diffraction, was produced by a. Hershey and Chase. b. Watson and Crick. c. Chargaff. d. Franklin. DNA: DNA, or deoxyribonucleic acid, is the principal molecule of her...
parameters such as ionic strength could play a direct role in adhesion of organic matter to mineral surfaces. This factor in organic–mineral binding is important to consider, as organic matter is transported through soils via water and water films and the interactions at mineral surfaces exhibit ...
<B>The cover picture shows</B> the supramolecular tetramer that exists as a repeating motif in crystals of the crown ether quinoxaline derivative whose synthesis is shown on the left-hand side of the figure. As illustrated on the right-hand side of the graphic, a water molecule, held in ...
Sensitivityof Water Dynamics to Biologically SignificantSurfaces of Monomeric Insulin: Role of Topology and ElectrostaticInteractions. In addition to thebiologically active monomer of the protein insulincirculating in human blood, the molecule also exists in dimeric andhexameric forms that... Bagchi,Kushal...
The rate of evaporation of solvent determined as an increase of the number of one-molecule water clusters through a chosen time period was evaluated for the periods 0–36 ps, 36–72 ps, and 0–72 ps of production time. Figure 23 shows the results for all 24 systems under 1.5 V/nm. ...
Hydrolase is a term often used inbiochemistry. It refers to a specific class of enzyme that works to control the process ofhydrolysisin the body. Hydrolysis is basically a chemical reaction that is caused when a molecule of water works to split apart another molecule in the body. There are ...

(18F), with radioactive half-lives of 20 and 110 min, respectively. Due to these short half-lives, PET radioligands are generated in a cyclotron and are rapidly incorporated into the molecule of interest immediately prior to their use (8). In SPECT, the commonly used isotope is technetium...
