Q.1
Three given polypeptides (P, Q and R), of same size and same pl (7.2), have a
single aspartic acid in each of them. In polypeptide P, the aspartic acid residue is
on the surface. In polypeptide Q, it is surrounded by negatively charged residues,
whereas in polypeptide R it is deeply buried in a hydrophobic core. pKa of the side
chain carboxylate of free (in solution) aspartic acid is 3.65. The polypeptides are in
a buller of pH 7.4. The clange in pKa of the aspartic acid side chain carboxylate in
the polypeptides P, Q and R is likely to,
Ans
remain the same in P, modest increase in Q and greater increase in R
X2.
remain the same in all the three polypeptides
X3.
increase in P, decrease in Q and remain the same in R
X 4.
remain the same in P, increase Q and decrease in R.
