Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Selective detection for gas chromatography by ultraviolet spectrometry

Creator:: Van Engelen, Debra L.
Abstract:: Spectrometric detection systems for gas chromatography (GC) based on gas phase ultraviolet absorbance and fluorescence measurements have been developed and evaluated in this research. Polynuclear aromatic compounds (PNAs) are selectively detected by these systems. Limits of detection for PNAs range from 4 ng to 90 ng for absorbance determinations, and...

Design and development of an intensified diode array system and its application to new fluorometric reaction rate methods of analysis

Creator:: Ryan, Mary Andrieu
Abstract:: Improvements in instrumentation for fluorometric kinetic measurements and the application of a new intensified diode array (IDA) rapid scanning system to low level transient fluorescence measurements are reported. This instrumentation is applied to a new fluorometric kinetic method for thiamine (TM). Modifications to the existing fluorometric reation rate instrument include...

The synthesis and electrocyclization of some linear and cross-conjugated hexatrienes

Creator:: Hilton, Charles Bruce
Abstract:: As part of the continuing investigation of the thermal cis- 1, 3, 5-hexatriene to 1,3-cyclohexadiene rearrangement, four new trienes and a cross-conjugated pentaene have been prepared and their thermal reactions studied. A new route to the synthesis of highly substituted trienes has been developed. The synthesis of three of these...

The rotational motion of molecules in crystalline solids

Creator:: Miller, R. E.
Abstract:: Theoretical studies and experimental results are presented for the rotational motion of molecule's in crystalline solids. The group theory is solved for molecules of any symmetry matrix isolated at a site in a crystal field of any symmetry. As the potential terrier to rotation of the molecule relative to the...

A chemical study of the minerals from L-6 chondritic meteorites

Creator:: Curtis, David Ballantyne
Abstract:: Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

Chromatographic separation of alkaline earth metals using alpha-hydroxyisobutyric acid

Creator:: Hauschild, John Arthur
Abstract:: A systematic study of the elution of magnesium and calcium from Dowex 50 X 8 resin using α-hydroxyisobutyric acid (α-HIBA) at various pH values and concentrations, indicated that the difference in the equilibrium distribution coefficients of these two elements was large enough for a good separation. This fact was applied...
