22. LIPASES AND PHOSPHOLIPASES IN PHOSPHOLIPID SYNTHESIS
Abstract : The synthesis of phospholipids with defined fatty acid and polar head composition catalysed by lipases and phospholipases was investigated. Lipases from Rhizopus arrhizus and Candida antarctica were used for the direct acylation of DL-a-glycerophosphate and L-a-glycerophosphatidylcholine, with different fatty acids. READ MORE

23. Palladium(0)-Catalyzed Synthesis of Spirocycles and Supercritical Chemistry using a Resistively Heated Flow Reactor
Abstract : This doctoral thesis focusses on an effective and selective approach to the synthesis of spirocycles using palladium(0)-catalyzed Mizoroki-Heck reactions. In addition, selective and efficient chemistry was highlighted by the design and evaluation of a novel resistively heated system for continuous flow (CF) synthesis for high-temperature and high-pressure applications.

24. Regulation of the hepatic ACAT2 expression and roles of HNF1alhpa and HNF4alpha in cholesterol metabolism
Abstract : Acyl-Coenzyme A:cholesterol acyltransferases (ACATs) 1 and 2 are integral membrane proteins located in rough endoplasmatic reticulum that catalyzes the formation of cholesteryl esters (CEs) from cholesterol and long-chain fatty acids. ACAT1 is present in most tissues, whereas ACAT2 is confined to enterocytes and hepatocytes. READ MORE

25. Alkaliphilic Bacillus species and an alkaline active lipolytic enzyme
Abstract : The Great Rift Valley running through Eastern Africa contains a large number of soda lakes. These unique lakes constitute among the most stable alkaline environments with a dense and varied population of microorganisms. Such microorganisms are invariable alkaliphiles and are considered to be a promising source of enzymes with unique features. READ MORE
