The structure of a peptide is given below. If the absolute values of the net charge of the peptide at pH = 2 , pH = 6 , and pH = 11 are z 1 , z 2 , and z 3 , respectively, then what is z 1 + z 2 + z 3 ?

The structure of tripeptide will be as followed at $PH = 2$ (in highly acidic medium)

hence $|z_{1}| = 2$ at $pH = 6$ (in approximately neutral solution it will be

Hence $|z_{2}| = 0$ $pH = 11$ (in highly basic medium) the structure will be

Hence $|z_{3}|$ will be $3$ .

Therefore $|z_{1}| + |z_{2}| + |z_{3}| = 2 + 0 + 3 = 5$ .
