Each functional group is attached to an amino acid. If the functional group on the right was switched with an amino group, would the bond between the 2 still form?
Yes, because there is no difference in charges between any functional groups.
No, the amino group is negatively charged like the oxygen
Yes, the amino group's hydrogen will likely form a similar hydrogen bond.
No answer can be given with the information provided.
