How to work out isoelectric point
WebThe isoelectronic point will be halfway between, or the average of, these two pK a s, i.e. pI = 1/2 (pKa1 + pKa2). This is most readily appreciated when you realise that at very acidic pH (below pK a 1) the amino acid will have an overall +ve charge and at very basic pH (above pK a 2 ) the amino acid will have an overall -ve charge.
