| 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?
