4. C-terminus (pKa ~3.1): At pH 7.0, which is well above its pKa, the carboxyl group will be deprotonated and carry a -1 charge.
Summing these charges: (+1) + (0 for A) + (0 for T) + (0 for L) + (-1 for D) + (0 for A) + (+1 for K) + (-1 for C-terminus) = 0.
Therefore, the net charge of the peptide ATLDAK at pH 7.0 is 0.
The isoelectric point (pI) is the pH at which a molecule, such as a peptide, has no net electrical charge. Calculating the pI for ATLDAK involves considering the pKa values of all ionizable groups and finding the pH at which the sum of positive and negative charges is zero. For ATLDAK, the ionizable groups are the N-terminus (+1), Aspartic Acid side chain (-1), Lysine side chain (+1), and C-terminus (-1).
The pI is typically estimated as the average of the pKa values that bracket the point of zero net charge. In this case, the relevant pKa values are those of the Aspartic Acid side chain (pKa ~3.9) and the Lysine side chain (pKa ~10Hi everyone, I'm starting to approachpeptidesynthesis and I'm having trouble writing mypeptidesinto chemdraw with protecting groups..5), as well as the N-terminus and C-terminusDraw the peptide ATLDAK.
