It can be calculated by the average of the relevant p K a values as you have mentioned. Your confusion seems to stem from choosing the relevant p K a values. For this we should refer to the titration curve of the amino acid.
WebFeb 8, 2024 · Protonation of the α − group is followed by deprotonation of α −carboxylic acid group Using the pKa’s to find out the isoelectric point pKa1 + pKa2 +pKR 3 = 2.19 +9.67 + 4.25 3 = 5.37 This gives us an assumption that at pH = 1 the solution will be positive , at pH = 7 it’ll be negative and at pH = 13 it will may yield a charge of −2 WebThe isoelectric point is the point at which the overall charge of the protein is zero (a neutral charge). Separation of proteins at the isoelectric point is called isoelectric focusing. In isoelectric focusing a gradient of pH and an electric potential are applied across the gel, making one end more positive than the other.
