(3) Non-protein nitrogenous compounds: urea nitrogen, creatinine and uric acid.
Total nitrogen (TN) is estimated by adding all the nitrogenous compounds, including as ON, NH4N, and nitrate-nitrite-nitrogen.
aurantiacus is known to use ammonia as the sole nitrogen source, and several amino acids (nitrogenous compounds), but not nitrate, can enhance the growth.
The amino acids glutamine and glutamate are the main nitrogen donors for the biosynthesis of a wide variety of nitrogenous compounds.
The biochemical properties of amphibian skin toxins are highly varied, most being complex nitrogenous compounds.
The glomerular filtrate contains the nitrogenous compounds ultimately to be excreted in the urine.
Glands in the leaves secrete enzymes that digest the captured insects, and the leaves then absorb the nitrogenous compounds (amino acids) and other products of digestion.
The end products, particularly nitrogenous compounds and salts, are absorbed by the plants to enable their survival under otherwise marginal or hostile environmental conditions.
Metabolic wastes (carbon dioxide, water, oxygen, and nitrogenous compounds) diffuse through the cell membranes of these unicellular organisms into the outside environment.
Though some of these poisons are eliminated in their original chemical form, others, such as some nitrogenous compounds, are altered biochemically to less toxic compounds.
OPGs can remove COD and nitrogenous compounds without external aeration.
