Kinetic analysis of the induction period in lipoxygenase catalysis
(1993)
The dioxygenation of 50 pM linoleate at 0.1 pM (13s)-hydroperoxylinoleate, 240 pM 02, pH 10, and 25 O C , catalyzed by varying amounts of soybean lipoxygenase-1, was studied with rapid kinetic techniques. The aim was to ...
Determination of rafoxanide and closantel in ovine plasma by high performance liquid chromatography
(1993)
A high performance liquid chromatographic method has been developed for the determination of rafoxanide and closantel in ovine plasma. Acetonitrile and chloroform were used for the extraction. The mean recoveries were ...
Excited hydrogen and the formation of molecular-hydrogen via associative ionization. 1 : Physical processes and outflows from young stellar objects
(1993)
Rates for the associative ionization reaction H(n=2)+H→H2++e- are calculated. This reaction is found to be a greater contributor to the H2 formation rate than the direct radiative association reaction H(n=2)+H→H2+hν in ...
The free energy change of restricting a bond rotation in the binding of peptide analogues to vancomycin group antibiotics
(1993-01-01)
The adverse cost in free energy of restricting an internal bond rotation in the binding of the peptide ligands N-succinyl-D-alanine and N-fumaryl-D-alanine to the antibiotic Ristocetin A, has been estimated to be 3.7 ± 0.9 ...
An H I absorption survey of M31 and M33 - The mixture of warm and cool phases in the interstellar media of spiral galaxies
(1993)
The VLA in A-array is used to survey the nearby spiral galaxies M31 and M33 in the 21-cm line in order to measure absorption by the H I toward background continuum sources. Spectral line cubes with rms noise less than 1.2 ...
The expression of foreign DNA in bacteria
