i saw this question but is this much detail included in the exam? i never heard the charges in books before
Hi!
the (+) and (-) “cancel out” cause they’re zwitterions leaving Glycine and Alanine neutral
Lysine is positively charged:
(-) (+) (+) ---- (+) overall
Aspartate is negatively charged overall
i think this might not be expected of us to know, hope this helps!
