A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: The molecular formula of ammonium nitrate is NH4NO3. The molecular formula indica...

Powders of Al2O3, NaHCO3 K.HCO3, NH4H2PO4 and KCI were used. Particle diameters were in the range from 38 to 43 m. In order to obtain significant inhibition without extinguishing the flame, powder feeding rates of 3 mg/litergas were used for NaHCO3, KHCO3and NH4H2PO4; 2 mg/litre...
sedimentation, thus simulating reduced gravity conditions. Subsequently, metabolites and proteins were extracted and measured with mass spectrometry-based techniques. Our results emphasize the importance of certain signal transducer proteins, which showed higher abundances in cells grown under reduced gravity....
The Bacillus strain was fermented in standard small fermenters in a medium composed per liter of 6.5 g of KH2PO4, 4.5 g of Na2HPO4, 3.0 g of (NH4)2SO4, 2.0 g of Na3-citrate-2H2O, 3.0 g of MgSO4.7H2O, 6.0 ml of Mikrosoy-2, 0.15 mg of biotin (1 ml of 0.15 mg/ml ethanol)...

↑NH3+H2O≈NH4++OH−+H2O. [0051] However, because a mildly alkaline solution is formed in this case, some portion of the acidic reaction catalyst (typically phosphoric acid) will be converted to dihydrogen phosphate (H3PO4≈H++H2PO4−). On drying to form the intimate mixture of as...
For both strains, 13C8-6-MSA was incorporated into yanuthones D and E, resulting in a mass shift of 7.023 Da. This is in agreement with the scenario described above, where one carbon atom must be eliminated from 6-MSA in the biosynthetic processing toward yanuthones D and E. Moreover...
Results Isolation and analysis of urinary peptides by mass spectrometry (MS). To search for genotype-specific differences in the urinary peptidome, we isolated peptides from the urine of different mouse strains and fractionated them by high-perfor- mance liquid chromatography (HPLC). A fraction ...
