Definition of nitrogenous in US English:



  • Containing nitrogen in chemical combination.

    • ‘As the primary inorganic nitrogenous compound released from mineralized organic matter, ammonium plays, besides its nitrification product nitrate, a key role in N nutrition for plants and soil microorganisms.’
    • ‘Since the ferments are organized, it is possible that oxygen, acting as itself, is able to induce the production of the ferments through its contact with the nitrogenous materials, and therefore the ferments have arisen spontaneously.’
    • ‘The term ‘pharmaceutically acceptable amine salt’ contemplates salts with ammonia and organic nitrogenous bases strong enough to form salts with carboxylic acids.’
    • ‘During this process of rendering a condensate was produced which was nitrogenous.’
    • ‘Urea is a nitrogenous compound excreted in the urine by humans and most other mammals.’
    • ‘High sugar concentration represses expression of genes for photosynthetic components, which leads to the acceleration of senescence and re-translocation of nitrogenous compounds.’
    • ‘Under sulphur-deficient conditions, reduced protein synthesis is accompanied by the accumulation of organic and inorganic nitrogenous compounds.’
    • ‘This is the most important nitrogenous fertilizer.’
    • ‘When the body ‘burns' food the end products are mainly water and carbon dioxide, together with some nitrogenous chemicals such as urea.’
    • ‘Pulses are also necessary for sustainable agriculture, since they are nitrogen-fixing crops and provide an ecological alternative to chemical nitrogenous fertilizers.’
    • ‘They are made up of tightly coiled, double strands of DNA linked in a ladder-like structure with four nitrogenous chemicals: adenine, cytosine, guanine and thymine.’
    • ‘The nitrogenous bases belong to two classes of molecules - purines and pyrimidines.’
    • ‘Degraded nitrogenous compounds, mainly amino acids, are translocated to other organs, leading to reduction in the leaf nitrogen content.’
    • ‘Urine is easy to find by its strong odor - and it's a veritable cocktail of nitrogenous waste, amino acids, salts, and excreted sugars.’
    • ‘The majority of these signals can be assigned to amino acids and to nitrogenous metabolites derived therefrom.’
    • ‘The banana companies significantly increased their use of nitrogenous fertilizers, irrigation waters, and pesticides in order to ensure high yields of large, unblemished fruit.’
    • ‘Indeed, bacteria in the guts of extant termites are known to be able to convert the nitrogenous end product uric acid into metabolites usable by the host.’
    • ‘Although fish do not produce NaOH, they do excrete bases such as ammonia and other nitrogenous wastes as a result of their metabolism.’
    • ‘While nitrous oxide is created naturally in swampy soils, its leakage from fields is multiplied by the breakdown of nitrogenous fertilizers and the engine emissions of large farm machines.’
    • ‘That is, it is plausible to hypothesize that observations of altered plasma steroids in contaminant-exposed juvenile and adult alligators are, in part, a response to nitrogenous pollutants.’
