电喷雾质谱动力学方法测定磷酰化丙丙二肽的气相质子亲和能
Determination of the Gas-Phase Proton Affinity of N-Dipropyloxy-phosphoryl Alkyl-alanine by Electrospray Ionization Mass Spectrometry with the Kinetic Method
【Abstract】 In this work, the change of gas-phase proton affinity of alkyl-alanine through the phosphorylation reaction was studied by the electrospray ionization mass spectrometry with kinetic method. It was proved that the phosphorylation could increase the proton affinity of small peptide. A proposal that proton affinity increase might be responsible for the sensitivity improvement of small peptide in mass spectrometry has been provided.
