. In sequencing by mass spectrometry, not every peptide bond may break. a. If cleavage between two Gly residues does not occur, which amino acid would be identifi ed in place of the two glycines? b. What amino acid would be identifi ed if a bond between Ser and Val did not break (see Problem 75 for amino acid masses)? | Numerade

Mass spectrometry is more often applied to molecules than to atoms. We will see in Chapter 3 that the molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule. The mass spectrum of H2 is taken under conditions that prevent decomposition into H atoms. The two naturally occurring isotopes of hydrogen are ^1 H (atomic mass =1.00783 u; abundance .99.9885 %) and ^2 H (atomic mass =2.01410 u; abundance .0.0115 %). (a) How many peaks will the mass spectrum have? (b
