Trehalose – properties, biosynthesis and applications Malgorzata BUREK, Sylwia WAŚKIEWICZ, Ilona WANDZIK*, Klaudia KAMIŃSKA – Faculty of Chemistry, Silesian University of Technology, Gliwice, Poland
Please cite as: CHEMIK 2015, 69, 8, 469–476 A few decades ago it was thought that carbohydrates are just the source of energy. However, over the years it was revealed that many of them fulfill specialized biological functions. Trehalose, which was described for the first time in the 30s of the nineteenth century, turned...Cellulase immobilized on copolymers based on N-vinylformamide: Influence of immobilization on the catalytic activity of the enzyme

Aminopeptidases isolated from plants of great economic value – role and characteristics Joanna KANIA*, Danuta GILLNER – Faculty of Chemistry, Silesian University of Technology, Gliwice, Poland
Please cite as: CHEMIK 2015, 69, 8, 463–468 Aminopeptidases (EC 3.4.11.XX) belong to the group of proteases, important enzymes which play key roles in many life processes. They catalyze the hydrolysis of amino acids located at the N-terminus of peptide and are involved in proteins degradation to free amino acids. Leucine aminopeptidase...Release of active ingredients from cosmetic emulsions
Release of active ingredients from cosmetic emulsionsJoanna IGIELSKA-KALWAT*, Izabela NOWAK – Laboratory of Applied Chemistry, Faculty of Chemistry, Adam Mickiewicz University, Poznań, Poland Please cite as: CHEMIK 2015, 69, 8, 498–504 Fast development of cosmetic industry and increasing awareness about healthy appearance have prompted the need for improved quality of cosmetic products and stimulated development of new methods aimed at characterisation and performance of new products. One of the fundamental tests of cosmetic preparations is that for bioavailability, which permits determination of...
