To characterize parameters influencing the antioxidant activity at interfaces a novel ESR approach was developed, which facilitates the investigation of the reaction stoichiometry of antioxidants towards stable radicals. To relate the activity of antioxidants towards the location of radicals at interfaces NMR experiments were conducted. Micellar solutions(More)
The location and the resulting chemical microenvironment of the antioxidant propyl gallate (PG) was studied in micellar solutions using the cationic emulsifier cetyl trimethyl ammonium bromide (CTAB), the anionic emulsifier sodium dodecyl sulphate (SDS) and the non-ionic emulsifier Brij 58 (polyoxyethylene-20-cetyl ester). T 1 relaxation time of the(More)
The human Acyl-CoA binding protein (ACBP) is a structural and functional highly conserved protein. As an intracellular pool former and carrier of acyl-CoAs, ACBP influences overall lipid metabolism. Its nuclear abundance and physical interaction with hepatocyte nuclear factor 4alpha suggested a gene regulatory function of ACBP. To identify ACBP target genes(More)
The partitioning of SDS and CTAB in o/w emulsions was investigated by ultrafiltration (UF), dialysis and small-angle neutron scattering (SANS). It was possible to measure the monomeric and the micellar concentrations of the emulsifiers in the filtrate and permeate in the UF and dialysis experiments, respectively. In addition, the interfacial concentration(More)
In order to investigate the involvement of sulfated groups in the Trypanosoma cruzi host–parasite relationship, we studied the interaction between the major cysteine proteinase of T. cruzi, cruzipain (Cz), a sulfate-containing sialylated molecule and the sialic acid-binding immunoglobulin like lectin-E (Siglec-E). To this aim, ELISA, indirect(More)
