Photosensitivity responses of Sagittula stellata probed by FTIR, fluorescence and Raman microspectroscopy

Photosensitivity responses of Sagittula stellata probed by FTIR, fluorescence and Raman microspectroscopy - RSC Advances (RSC Publishing) Raman, fluorescence and FTIR experiments of prestine Sagittula stellata and Sagittula stellata–metal ion complexes grown in light and in dark were performed to probe the photosensitivity response of the cellular components in the marine bacterium. In the presence of Cu(ii) and Zn(ii) the frequency...

Modifications of hemoglobin and myoglobin by Maillard reaction products (MRPs) by Aristos Ioannou and Constantinos Varotsis

Modifications of hemoglobin and myoglobin by Maillard reaction products (MRPs) High performance liquid chromatography (HPLC) coupled with a Fraction Collector was employed to isolate Maillard reaction products (MRPs) formed in model systems comprising of asparagine and monosaccharides in the 60–180°C range. The primary MRP which is detected at 60°C is important for Acrylamide…
