Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

Creator:: Venier, Lynn Corrine
Abstract:: In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...

The infrared spectrum of the nitrate ion in various crystalline environments

Creator:: Stewart, Julie Lingscheid
Abstract:: The infrared absorption spectra in the out-of-plane bending (v₂) region of potassium nitrate were studied for three phases. Several types of sampled were used: nujol mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The existence of three of the reported polymorphic phases was confirmed by the spectra. The transitions between phase...

Bioactivity Screening and Gene Activation Strategies in Fungi

Creator:: Coddington, Nathan C.
Abstract:: Natural products from plants, bacteria, and fungi play an important role in society. Over the last 35 years, natural products and their derivatives have inspired over 60% of all FDA approved small-molecule drugs, and are among the top prescribed therapeutics.1-2 Fleming’s discovery of the fungal antibiotic penicillin started the “Golden...

The analytical application of the galvanic dissolution of niobium and tantalum : the determination of nitrogen

Creator:: VanSanten, Richard Theodore
Abstract:: Nitrogen is a contaminant of niobium and tantalum adversely affecting the workability of the metal. With recent interest in the refractory metals, one problem the chemical analyst must solve is the accurate determination of nitrogen in niobium and tantalum at very low levels. The usual method of assaying for nitrogen...
