Question

31
Estimate the net charge of a peptide Ser-Glu-Pro-Ile-Met-Ala-Pro-Val-Glu-Tyr-Pro-Lys at pH 7.0 and at pH 12.0
Typical ranges observed for pk, values of groups in protein: a-carboxyl group (3.5-4.0), side chain carboxy
group (4.0-4.8), c-amino group (8.0-9.0), phenolic group (9.5-10.5), side chain amino group (9.8-10.4).
b. -4, -1
C. -4 -4
d. -1,-1
P. -1, -4​
