Meanings of nh4 in английском

The presence of K+ or NH4+ is essential for the enzyme reaction.

Ammonium bromide, NH4Br, can be prepared by the direct action of bromine on ammonia.

However, enhancement of the IT by NH4Cl only occurred when the pH rose above neutrality.

With the chemical formula NH4NO3, it is used mainly for fertilising farmland.

The epithelial response to an alkalizing substance was prevented by simultaneous feeding of the acidifying salt NH4Cl.

The widely applicable monitoring concept will be illustrated with examples for an ion-sensitive NH4+- and a MLSS-sensor.

Ammonium persulphate (NH4)2S2O8 has been prepared by H. Marshall (Jour.

In the presence of bafilomycin the alkalinizing effect of osmotic cell swelling was not reversible, in contrast to that of NH4Cl.

The hydrosulphide NH4.HS can be obtained as a white solid, by mixing well-cooled ammonia with a slight excess of sulphuretted hydrogen.

These observations suggest that amino acid methyl esters are more effective probes to investigate lysosomal function in cultured myocytes than chloroquine or NH4Cl.

Diammonium hydrogen phosphate, (NH4)2HPO4, is formed by evaporating a solution of phosphoric acid with excess of ammonia.

The salts produced by the action of ammonia on acids are known as the ammonium salts and all contain the compound radical ammonium (NH4).

At the other two, the wastewater has also been treated biologically resulting in lower concentrations of BOD7 and NH4+-N.

Ammonium sulphate (NH4)2SO4 is prepared commercially from the ammoniacal liquor of gas-works (see GAS: Manufacture) and is purified by recrystallization.

The tissue-plasma concentration ratios (Kp) of these drugs in various tissues were determined by infusion studies at steady-state in the presence or absence of NH4Cl.

Ammonium dihydrogen phosphate, NH4.H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acid.
