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. WebThis biochemistry video tutorial explains how to calculate the isoelectric point of amino acids. It also explains how to identify the zwitterion structure of an amino acid. Show …

There is an internal transfer of a hydrogen ion from the -COOH group to the -NH 2 group to leave an ion with both a negative charge and a positive charge. This is called a zwitterion. This is the form that amino acids exist in even in the solid state.
