41. Syn addition is favored with 99 % nitro group hydrogen bonded to the protonated amine in the proline side group. 42. The lone pair from the pyridine nitrogen pushes electron density to the gamma carbon, which is protonated by lysine. 43. The empirical formula of TGS does not represent the molecular structure, which contains protonated glycine moieties and sulfate ions. 44. Consequently, encapsulated molecule can be easily protonated as a resulting carbocation from protonation is stabilized by the surrounding anions. 45. When a molecule is protonated or deprotonated, the geometry and electronic structure is changed, and AES spectra reflect this. 46. In the reduced form of plastocyanin, His-87 will become protonated with a pK a of 4.4. 47. Protonated hydrazine "'2 "'protonates the oxygen of one of the carbonyl groups of the imide.48. By varying the shape and size of the cavity the protonated polyamine can be engineered to be a specific anion receptor. 49. *When dopamine in solution is mixed with hydrochloric acid, it becomes protonated and forms a highly soluble hydrochloride salt. 50. When the carboxylic group and the amino group are both protonated , what prevents enolization from occuring and attacking the formaldehyd?
