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.
