Peptide or protein involved in biomolecules function different types from the structure of the original materials. The purpose of this research is to study the three-dimensional structures of the biomolecular ions in reactions with gaseous molecules. We studied proton transfer reactions of insulin (Ins) ions and insulin chain B (Ins B) ions in the gas phase. We used a tandem mass spectrometer with electrospray ionization (ESI). We changed temperature, retention time in the collision cell, and DC voltage of octapole ion guide (DC-OPIG) of the cell. The target molecules used were 1, 4-butanediamine (Bda). By changing DC-OPIG, remarkable change was observed for reaction rate constants and distribution of product ions.
