Chapter 14, Problem 14.38P
Interpretation Introduction

Interpretation:

The protein (P) gives a three type of cluster and what mass-charge values do these clusters appear in the mass spectrum, the correct reason has to be explained with the given molecular mass values.

Concept Introduction:

Electrospray ionization (ESI):

  • • This technique used in mass spectrometry to produced different ions.
  • • It is especially useful in producing ions from macromolecules because it overcomes the propensity of these molecules to fragment when ionized.
  • • The primary ion source used in liquid chromatography-mass spectrometry, because it is liquid-gas interface that is capable of coupling liquid chromatography with mass spectrometry. 

Mass spectrum: It generates multiple ions from the sample under investigation, it than separates them according to their specific mass to charge ration (m/z) and records the relative abundance (RA) of each ion types.

Mass spectrometry and X‑ray diffraction are common biochemical techniques for characterizing proteins. Classify each statement based on whether it applies to mass spectrometry, X‑ray diffraction, or both techniques.
Because of the sensitivity of mass spectrometry, it is often used to detect the presence of drugs in blood, urine, or other biological fluids. Tetrahydrocannabinol (nominal mass 314), a component of marijuana, exhibits two strong fragment ions at mlz 246 and 231 (the base peak). What is the likely structure of each ion? HO, CH3 H H,C H,C CH, Tetrahydrocannabinol
Determine the net charge of the predominant form of Asp at (a) pH 1.0, (b) pH 3.0.
