pressure. The colorless crystals are freely soluble in water and in most organic solvents, with the exception of petroleum ether. The same compound can for example also be ;0 obtained by the action of pyridine-2:3-dicarboxylic acid-dichloride on an aqueous diethylamine solution. In analogous...
Why is acetone miscible with both water and soap solution? What is distillation? Describe some of its practical applications. Why is lidocaine a better nucleophile than diethylamine? Give one reason why ^{13} C NMR is less sensitive than ^1 H NMR spectroscopy. Why the presence of H_2SO_4...

Homogenates were then diluted 1:1 in diethylamine (DEA) buffer (0.4% diethylamine, 100 mm NaCl) and re-homogenized (6 strokes), and 1 ml aliquots were centrifuged at 100,000 × g at 4 °C for 1 h. DEA-containing supernatants were removed and neutralized by addition of 1/10th volume ...
000 g centrifugations was loaded on columns. Columns were sequentially washed with 30 volumes lysis buffer, 20 volumes 10 mM Tris 0.5% triton X-100 300 mM NaCl pH 8, 20 volumes 10 mM sodium phosphate 0.5% triton X-100 450 mM NaCl pH 10, and eluted with 0.05 M diethylamine 0.5% ...
Recent reports suggest that vitamin B1 (thiamine) participates in the processes underlying plant adaptations to certain types of abiotic and biotic stress, mainly oxidative stress. Most of the genes coding for enzymes involved in thiamine biosynthesis in Arabidopsis thaliana have been identified. In our...
