11. Flocculation with Polyelectrolytes in Latex and Microbial Systems
Sammanfattning : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. LÄS MER
12. Metabolism and Biological Monitoring of Organic Acid Anhydrides
Sammanfattning : The aim of this thesis was to describe the metabolism and to develope methods for biological monitoring for two organic acid anhydrides (OAAs), namely hexahydrophthalic anhydride (HHPA) and methylhexa-hydrophthalic anhydride (MHHPA). The OAAs are reactive, low molecular weight chemicals used in vast quantities in the industry. LÄS MER
13. Monoglyceride Lipase and Hormone-Sensitive Lipase - Molecular and structural aspects
Sammanfattning : Triglycerides in the adipocyte are hydrolysed by means of three consecutive reactions through the combined action of two lipases: hormone-sensitive lipase (HSL) and monoglyceride lipase (MGL). HSL catalyses the first and rate-limiting step, i.e. LÄS MER

15. Selenium Compounds in Milk. Studies of Selenoproteins, Selenium Enrichment and Oxidative Stability of Food
Sammanfattning : Selenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. LÄS MER
