The molecular weight of horse myoglobin is 16,951.49 Daltons. Intact proteins analysed by ESI-MS exhibits multiple charges distribution.a. Calculate the expected m/z [M+15H]15+ ion of the horse myoglobinb. If you were to identity the myoglobin protein by ESI-MS from across differentspecies, and you observe the ion m/z 1,413.6241, would you identify it as the horsemyoglobin or the sperm whale myoglobin (17,199.91 Da)?
