In ion-exchange chromatography, amino acids are separated on the basis of electro-
static interactions and hydrophobic interactions with the resin. The chemical structure of the resin pol-
ymer with a negatively charged sulfonic acid group is shown to the right. An elution profile for the amino
acids using this resin is given below. Based on the elution profile above, explain the following:
