چکیده
( 1 ) die weitaus beste Vorstufe für Cyanidin. Da der prozentuale Anteil von Trit ium an C-2 und C-3 von 1 unbekannt ist und dieses Tritium be im Ubergang in Cyanidin verloren gehen muß, läßt sich eine genaue Einbaurate von 1 nicht angeben. Sie muß aber auf jeden Fall höher liegen als die gemessenen Werte. Im Gegensatz zu den früheren Ergebnissen mit Keimlingen ist der Unterschied des Einbaus von 1 zu Phenylalanin signifikant besser, so daß 1 als echte Zwischenstufe der Cyanidinbiosynthese angesehen werden kann. Mögliche Reaktionswege für die Umwandlung von 1 in Cyanidin sind bereits früher diskutiert worden 1 7 .

The investigation of pyrocatechol electrochemical mechanism in presence of nitrite ion on platinum electrode
In this study, the electrochemical mechanism of catechol in presence and absence of nitrite ion, is investigated in phosphate buffer medium (pH=7) using platinum electrode through cyclic voltammetry method in various scan rates. Electrochemical oxidation of catechol showed how quinone has changed to o-benzoquinone and also how o-benzoquinone has reacted with nitrite ion and potential scan rate ...
متن کاملHydrogenase-Mediated Activities in Isolated Chloroplasts of Chlamydomonas reinhardii.
Isolated intact chloroplasts of Chlamydomonas reinhardii were found to catalyze photoreduction of CO(2) in the presence of 3-(3,4-dichlorophenyl)-1,1-dimethylurea when adapted under an atmosphere of H(2) demonstrating the association of a hydrogenase and anaerobic adaptation system with these plastids. The specific activity of photoreduction was approximately one third that detected in cells an...

Octyl methoxycinnamate is one of the ingredients in sunscreen products. The main aim of this study was to investigate the effect of different enhancers of in vitro skin permeability of Octyl methoxycinnamate. Octyl methoxycinnamate permeability parameters were evaluated through the whole skin of the rat with and without chemical enhancers including eucalyptus oil, urea, menthol and olive ...
متن کاملPhotoreduction of Potassium Dichromate in Aqueous Solution using Cobalt doped ZnO Nanoparticles
Co-doped ZnO nanoparticles with different Cobalt contents were prepared by direct precipitation method. The materials were characterized by XRD, SEM and TEM techniques. The XRD results indicated that the particle size of pure ZnO and Co-doped ZnO is about 30-45nm. The toxic Cr(VI) in industrial wastewaters can be removed by a reduction from Cr(VI) to Cr(III). The reduction of Cr(VI) to Cr(III) ...
متن کاملInvestigations of Calcium Aluminate Slag Penetration to MgO Monolithic Refractories in Steelmaking Process
In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...
