(Answered) The dissociation constants for a previously uncharacterized

Academics

The dissociation constants for a previously uncharacterized racemic amino acid discovered in a meteor have been determined to be pKa1=2.0, pka2=3.5,pka3=6 .3, pka4=8.0,pka5=9 .8 and pka7=10 .9.

A. What carbonyl or amino functional group would you expect to be associated with each dissociation?

B. What would be its approximate net charge on this amino acid at a pH of 2?
