What's the difference between odorant and odour?

Odorant


Definition:

  • (a.) Yielding odors; fragrant.

Example Sentences:

  • (1) Experiment 3 showed that the color-induced increase in odor intensity is not due to subjects' preexperimental experience with particular color-odor combinations, because the increase occurred with novel ones.
  • (2) Because of the wide range of human nasal anatomic configurations, some people sniff odorants against comparatively high resistances.

  • (8) Chemosensory cilia of olfactory receptor neurons contain an adenylate cyclase which is stimulated by high concentrations of odorants.
  • (9) Distal stimuli emanating from the female or pups induce proximity by provoking orientation, attention and arousal; the meaning of these stimuli is largely learned by conditioned associations during the initial executions of the behavior, although odors may have a prepotent influence for some individuals.
  • (10) The cyclic adenosine nucleotide pathway is turned off by kinase A activity, whereas the inositol trisphosphate cascade is terminated by kinase C. The data support the concept that desensitization of odorant responses involves phosphorylation of key elements in the transduction cascade.

  • (15) At 2.5 L min-1 both groups were able to track the buildup of odor intensity during infusion and its decline after infusion.
  • (16) Experiments 2 and 3 investigated whether desensitized animals could behaviorally detect and discriminate odors.
  • (17) No differences have been observed about aspect, odor, pH and volume of ejaculate.
  • (18) Determining specific ligand-receptor relationships is an extremely challenging task given the diversity of odorants able to be perceived and the potentially large size of the family of receptors.
  • (19) This review discusses the state of knowledge in odor memory within the framework of mainstream memory research.
  • (20) When heart rate is used as the index of conditioning, rat pups younger than 15 days of age do not display an odor-shock association.

Odour


Definition:

Example Sentences:

  • (1) Employed method of observation gave quantitative information about the influence of odours on ratios of basic predeterminate activities, insect distribution pattern and their tendency to choose zones with an odour.
  • (2) There was a clear relationship between the receptor responses and odour concentration.
  • (3) produced strong rotten, fishy, hydrogen sulphide off-odours.
  • (4) This may be managed in future by an odour-reducing minimal APS-addition under a 2%-application.
  • (5) • Rules requiring local authorities to investigate and abate noise, dust and odour nuisances will be liberalised or improved.
  • (6) Distinction was made between different types of odours (rotten, wood).
  • (7) These laboratory bioassay findings agree with field observations on tsetse responses to certain chemical odours.
  • (8) A substantial improvement in the rate of detection of organic lesions affecting the olfactory pathway can be achieved by substituting odours such as musk ketone, exaltolide, linalyl acetate and coumarin for those in current use.
  • (9) One month later the subjects underwent a second recognition test, at the end of which they were required to give an evaluation of the pleasantness of each odour on a nine-point scale.
