Interpretation: The overall charge of a polar neutral amino acid at a pH above its pI.
Concept introduction:
➢ Amino acid: Any molecule contains both amino and acid group
Ex:
➢ The group is polar then called polar amino acid.
➢ The amino acid has two groups
One acts base and other acts as acid. So net charge or form of amino acid depends upon
➢ Amino acid is any molecule that contains both amino and acid group. If net charge on amino acid is zero called zwitterion form contains equal no of charge.
➢ If , then at this
➢ acts as acid and donates one proton
➢ to form
And it has total charge
➢ If, then
Acts as base and accept one proton form solution and convert to
. So at such
it has total charge
