1. Crystallization of Parabens : Thermodynamics, Nucleation and Processing
Sammanfattning : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. LÄS MER
2. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media
Sammanfattning : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. LÄS MER
3. Structural Studies of Three Glycosidases
Sammanfattning : Glycosidases hydrolyse the glycosidic bond in carbohydrates. Structural studies of three glycosidases with different substrate specificities are presented in this work.Dextranase catalyzes the hydrolysis of α-1,6-glycosidic linkage in dextran polymers. LÄS MER
4. β-alanine synthase : one reaction, two folds and mechanisms
Sammanfattning : beta-alanine synthase (betaAS) is the third enzyme in the reductive pyrimidine catabolic pathway which is responsible for the breakdown of pyrimidine bases, including several anti-cancer drugs in higher organisms. We have solved the high resolution structures of two beta-alanine synthases that perform the same reaction but have two very different folds and utilize different reaction mechanisms. LÄS MER
5. BIOACTIVE ORGANOMETALLIC COMPOUNDS
Sammanfattning : Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. LÄS MER
