Glutamine is formed if an ammonium ion attacks the acyl-phosphate intermediate, while glutamate is remade if water attacks the intermediate.
22.
If the pH is low, the equilibrium shifts to the right : more ammonia molecules are converted into ammonium ions.
23.
During chronic acidosis, glutaminase is induced in the kidney, which leads to an increase in the amount of ammonium ions excreted.
24.
The salts produced by the action of ammonia on acids are known as the ammonium ion ( NH 4 + ).
25.
Glutaminase is also expressed in the epithelial cells of the renal tubules, where the produced ammonia is excreted as ammonium ions.
26.
Ammonium ion binds more strongly than water to GS due to electrostatic forces between a cation and a negatively charged pocket.
27.
The nitrogen atom features a lone electron pair that can bind H + to form an ammonium ion R 3 NH +.
28.
The addition of an H + ion to an ammonia molecule of the solvent creates its conjugate acid, the ammonium ion, NH.
29.
Beijerinck also discovered nitrogen fixation, the process by which diatomic nitrogen gas is converted to ammonium ions and becomes available to plants.
30.
Free ammonia ( NH 3 ), existing as the ammonium ion ( NH 4 + ) in blood, is toxic to life forms.
