What is "nitrogenous"

Usage examples of "nitrogenous".

Mushroom, is the kind most commonly eaten in England, being highly nitrogenous, and containing much fat.

But when there is a good proportion of manure from well fed animals in the heap, carbonate of ammonia is formed from the nitrogenous compounds in the manure, and this ammonia unites with the humic and ulmic acids and forms humate and ulmate of ammonia.

Sugars, acetone bodies, creatine, nitrogenous compounds, haemoglobin, myoglobin, amino acids and metabolites, uric acid, urea, urobilinogen and coproporphyrins, bile pigments, minerals, fats, and of course a great variety of psychotropic drugs: certainly all of the ones proscribed by the US Federal Bureau of Narcotics.

Altogether I experimented on sixtyfour leaves with the above nitrogenous fluids, the five leaves tried only with the extremely weak solution of isinglass not being included, nor the numerous trials subsequently made, of which no exact account was kept.

Drosera are continually secreting viscid fluid to replace that lost by evaporation, yet they do not secrete the ferment proper for digestion when mechanically irritated, but only after absorbing certain matter, probably of a nitrogenous nature.

Inflection of the exterior tentacles owing to the glands of the disc being excited by repeated touches, or by objects left in contact with them--Difference in the action of bodies yielding and not yielding soluble nitrogenous matter--Inflection of the exterior tentacles directly caused by objects left in contact with their glands--Periods of commencing inflection and of subsequent reexpansion--Extreme minuteness of the particles causing inflection--Action under water--Inflection of the exterior tentacles when their glands are excited by repeated touches--Falling drops of water do not cause inflection.

If it has been made to shut merely by one of the sensitive filaments having been touched, or if it includes an object not yielding soluble nitrogenous matter, the two lobes retain their inwardly concave form until they reexpand.

Dionaea the absorption of nitrogenous matter causes the lobes to press together with extreme slowness, whilst a touch excites rapid movement.

The pressure from fragments of glass excites movement almost as quickly as the absorption of nitrogenous matter, but the degree of incurvation thus caused is much less.

Various nitrogenous organic fluids and salts of ammonia induce aggregation, but in different degrees and at very different rates.

Altogether I experimented on sixtyfour leaves with the above nitrogenous fluids, the five leaves tried only with the extremely weak solution of isinglass not being included, nor the numerous trials subsequently made, of which no exact account was kept.

The inflection excited by the other salts of ammonia is probably due solely to their nitrogen,--on the same principle that nitrogenous organic fluids act powerfully, whilst nonnitrogenous organic fluids are powerless.

On the other hand, the secretion from glands excited by contact with nitrogenous solids or liquids is invariably acid, and is so copious that it often runs down the leaves and collects within the naturally incurved margins.

I may here add, as showing that the leaves are not acted on by the odour of nitrogenous substances, that pieces of raw meat stuck on needles were fixed as close as possible, without actual contact, to several leaves, but produced no effect whatever.

I have repeatedly found that the tentacles remain clasped for a much longer average time over objects which yield soluble nitrogenous matter than over those, whether organic or inorganic, which yield no such matter.
