â€‹â€‹â€‹â€‹â€‹â€‹â€‹Mass spectrometry is a very accurate means ofdetermining the mass and sequence of peptides, however someinconsistencies occur due to incomplete reactions and similarstructures.
a. Name two amino acids whose mass canâ€™t bedistinguished by mass spectrometry.
b. If a bond between Ser and Val is not hydrolyzed, whatamino acid could be mistakenly identified?
c. If a bond between two Gly residues is not hydrolyzed,what amino acid could be mistakenly identified?

a Answer Leucine and isoleucine Leucine and isoleucine are isomers of each other This means that they have different structures but have the same molecular formula and thus the same molecular mass Since mass spectrometry differentiates on the basis of mz ratio thus these two amino acids cannot be differentiated See Answer
