WebAmino acids are amphoteric molecules, that is, they have both basic and acidic groups. Monoamine and monocarboxylic acids are ionized in different ways in solution, depending on the pH of solution. At pH 7, the “zwitterions” H+ N – CH – COO- is the predominant species of Glycine in solution and the overall molecule is electrically neutral. Webthose that contain a carboxyl group, the COOH group, like acetic acid and benzoic acid. For weak acid reactions: HA + H2O R H3O + + A− Ka = [H3O +][A−] < < 1 [HA] ¾ Write the Ka expression for acetic acid. (Note: Water is a pure liquid and is thus, left out of the equilibrium expression.)

WebIonizing groups Some, but not all amino acids have R-groups that can ionize. The charge of a protein then arises from the charges of the amine group, the carboxyl group, and the sum of the charges of the ionized R-groups.
