The rate constants for the formation of CH3CHOCH3CO+ by both CH3COOH2+ and CH3CO+ from n-propyl acetate were larger than those for CH3COOC3H7CH3CO+ by a factor of four. CH3CHO+ and CH3CO+ from acetaldehyde did not participate in the acetyl ion transfer reaction leading to the ...

The product may affect the acidity (pH-factor) in water with risk of harmful effects to aquatic organisms. Bioaccumulation/ Accumulation: No information available. Mobility: Will likely be mobile in the environment due to its water solubility. ...
Which of the following statements are correct? (Choose all that apply.) a) As At pH 7, the peptide Met-Arg-Lys-Ser has a net charge of (a) -2. (b) -1. (c) 0. (d) +1. (e) +2. What is the anti-hemophilic factor ...
MS of hLCN2-R-NTD utilized a 7 T Fourier transform ion cyclotron resonance instrument equipped with an ESI source (Bruker). Proteins were desalted as described previously (26) and electrosprayed from 1 μm solutions in 1:1 H2O/CH3OH at pH 2.5 (adjusted by the addition of CH3COOH). From...
After stirring for 5 min, one drop of CH3COOH was added and the reaction was stirred overnight at room temperature. The solvent was removed and the residue was purified by preparative thin layer chromatography to afford the title compound as a white solid (20 mg)....
