Finding Z Value with Mass Spectra of Protein Fragments

Click For Summary
SUMMARY

This discussion centers on analyzing mass spectra of protein fragments to determine the Z value using m/z ratios. It is clarified that one should only consider the mass of the specific fragment responsible for the peak of interest, rather than the entire protein mass. This distinction is crucial for accurate calculations in mass spectrometry. The conversation emphasizes the importance of focusing on individual fragment masses for precise Z value determination.

I am given 2 mass spectra of protein fragments and don't get how to analysis a mass spectrum of a protein and find Z value with the given m/z ratios.

do i take the mass of the whole protein and divide by the m/z on the spectrum to find z?

thanks

No. Only the mass of the fragment responsible for the peak of interest.
