hi satish this is vikram,as u might know that arginine carry one positive charge,i.e.polarity at pH 7&all amino acid are dipolar;when an amino acid titrate with acid or base it shows constant pH only in certain range,after that it will behave normally and on addition of acid/base it will change in pH,that is isoelectric pH. u can refer Mathew's Biochemistry book for graph of acid-base titration On Sun, Nov 2, 2008 at 7:10 PM, Satish <[EMAIL PROTECTED]> wrote:
