The phrase "acid nitrogen" is correct and usable in written English.
It is typically used in scientific contexts, particularly in chemistry and biology, to refer to nitrogen compounds that can donate protons (H+) in a solution.
Example: "The analysis revealed high levels of acid nitrogen in the soil, indicating potential issues with nutrient availability for plants."
Alternatives: "acidic nitrogen" or "nitrogen in acidic form".
They are deficient in phosphoric acid, nitrogen, and humus but not in potash and lime.
The benzoic acid nitrogen mustard peptide conjugate vesicles may have potential in the treatment of cancers.
There are only a few non-cryogenic oxidizers available: red fuming nitric acid, nitrogen tetroxide, and hydrogen peroxide are the obvious choices.
HAI supplementation increased concentrations of peptide nitrogen and amino acid nitrogen, and reduced ammonia concentration (P<0.05), and decreased peptidase and deaminase activities (P<0.05).
Benzoic acid nitrogen mustard peptide (AAAK) conjugate was designed and synthesized, which was found to self-assemble into vesicles in water.
Near-infrared (NIR) spectroscopy was successfully applied to the rapid chemical-free determination of amino acid nitrogen (AAN) in tuber mustard.
On d 8, 9, and 10 of each period, digesta effluent samples were taken for ruminal NH3, volatile fatty acids, nitrogen metabolism analysis, and long-chain FA and AA flows.
The low mushroom production gap on wheat straw may be due to the inability of P. eryngii mushroom to produce hydrolyzing enzyme, which converts the wheat straw to utilizable amino acids, nitrogen, and carbon compounds necessary for the growth.
In fungi, GPCRs sense diverse extracellular signals including: pheromones, carbohydrates, amino acids, nitrogen sources and photons [ 24, 25].
Genes expressed at higher levels in the later stages (profile 10) function in arginine and glutamate transport, consistent with remobilization of amino acids (nitrogen) from the senescing tissues.
Oligopeptides can be used as source of amino acids, nitrogen and carbon, and their transporters have been documented in bacteria, fungi and plants.
