A protein engineering team compares two purified proteins that share identical amino acid composition but differ in sequence order. Both proteins lack cysteines and show similar overall size by mass spectrometry. One protein resists backbone cleavage under mild acid conditions more than the other. Assuming no post-translational modifications, which statement best links peptide bonds and primary structure to the observed difference in stability?
