Write the structure of alanine at pH =2 and pH =10. |
Answer» Solution :Alanine exists as a zwitterison (I) in aqueous solution. In presence of acid `(pH=2)`, the basic `-COO^(-)` GROUP ACCEPTS a proton to give cation (II) but in presence of a base `(pH=10)`, the acidie `-overset(N)H_(3)` group donates a proton to the base and THUS exists as an anion (III).
