WebCh27: Isoelectronic point. Isoelectronic point, pI. The isoelectronic point or isoionic point is the pH at which the amino acid does not migrate in an electric field. This means it is the pH at which the amino acid is neutral, i.e. the zwitterion form is dominant. A table of pK a and pI values can be found on the next page. Webthe side chain of tyrosine $-CH_2\mbox-Ph\mbox-{\scriptsize (p)}OH$ is an even weaker acid $[R\mbox-OH \rightleftharpoons R\mbox-O^- + H^+]$ so the IEP is 5.66; And every amino acid has more or less contribution to the IEP of a protein.
