Vedclass · Answer

(D) The correct answer is $ (D) $.An isoelectric point is defined as the $ pH $ at which a particular molecule carries no net electric charge.Amino acids contain both an amino group (which can form a cation) and a carboxylic group (which can form an anion).At the isoelectric $ pH $:$ 1. $ The net charge on the molecule is zero because the cationic and anionic charges are equal.$ 2. $ The concentration of the cationic form and the anionic form are equal.$ 3. $ The molecule exists primarily in its di-polar form,known as the Zwitter ion,which reaches its maximum concentration at this $ pH $.Therefore,all the given statements are correct.
