| 21. | More acidic donors can act as general or specific acids, which activate electrophiles by protonation.
|
| 22. | However, in acidic environments, protonation of the amino groups leads to an increase in solubility.
|
| 23. | Yellow can be produced by the protonation of a triaryl pyridine, such as Copikem Yellow 37.
|
| 24. | In this step, the hydride attacks Nitrogen on the flavin, which allows for another protonation.
|
| 25. | This is followed by further protonation when the hydride attacks a nitrogen atom on the flavin mononucleotide3.
|
| 26. | Most methods of illicit production involve protonation of the hydroxyl group on the ephedrine or pseudoephedrine molecule.
|
| 27. | It can be considered as a deenergized protonation reaction intermediate for the HeH + + CO ?
|
| 28. | The protonation steps between the arsenate and arsenic acid are similar to those between phosphate and phosphoric acid.
|
| 29. | These words are analogous to protonation and deprotonation, but they have not been widely adopted by chemists.
|
| 30. | DHFR catalyzes the transfer of a hydride from NADPH to dihydrofolate with an accompanying protonation to produce tetrahydrofolate.
