WebSep 7, 2024 · Isoelectric point (pI): The pH at which the net charge on the protein is zero. For a protein with many basic amino acids , the pI will be high, while for an acidic protein the pI will be lower. Isoelectric focusing is a type of zone electrophoresis, and it is usually performed in a gel, that takes advantage of the fact that a molecule's charge ...

WebTo get the proportion of acid A that is protonated, we need to calculate the ratio of protonated acid to all acid species. If we set the amount of protonated acid, HA, to 1, then by the equation above, [A⁻] is equal to 10 ( p H − p K a) so the ratio is: [ HA] [ HA] + [ A −] = 1 1 + 10 ( p H − p K a) WebWe are referred to a table that gives us the following information: p K a 1, C O O X − = 2.28 p K a 2, N H X 3 X + = 9.21 p I = 5.74
WebThe isoelectric point (pI) is the pH value at which the molecule carries no electrical charge. The concept is particularly important for zwitterionic molecules such as amino acids, peptides, and proteins. For an amino acid, the isoelectric point is the average of pKa values for the amine and the carboxyl group.

The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I). However, pI is also used. For brevity, this article uses pI. The net charge on the molecule is affected by pH of its surrounding environment and can become more positively or negatively charged due to the gain or loss, respectively, of protons (H ).
