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...

Interconversions of monoterpenes in peppermint

Creator:: Burbott, Alice Joyce
Abstract:: The analysis of the distribution of monoterpenes through the leaf pairs of a single shoot of Mentha piperita supports Reitsema's contention that the first terpenes formed are unsaturated ketones and that saturated terpenes are produced from these. The growth of Mentha piperita under varying conditions of temperature and the leaf-by-leaf...

The biosynthesis of terpenes in Pelargonium graveolens

Creator:: Allison, Robert David
Abstract:: Pelargonium graveolens Ait., rose geranium, contains several oxygenated monoterpenes, most of which are related to each other structurally. In this work, the metabolism and interconversions of these terpenes was investigated. A chromatographic analysis of geranium oil was performed initially for the purposes of identifying the terpenes and determining which chromatographic...

Low temperature thermal analysis of some boron halide complexes with weak Lewis bases

Creator:: Lerch, Ronald Edwin
Abstract:: Thermal analysis was used to investigate the following seven systems: H₂S-B₂F₄, SOF₂-B₂F₄, COC1₂-B₂F₄, SF₄-B₂F₄, Xe-BF₃, NF₃-BF₃, and NF₃-BC1₃. In two of the seven systems compound formation was observed. In the system, H₂S-B₂F₄ the compounds H₂S[superscript .]B₂F₄ and 2H₂S[superscript .]B₂F₄ are formed. The compound H₂S[superscript .]B₂F₄ has a melting point of...
