Exempel på hur man kan använda ODORANT i en mening

• Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the "smell of natural gas" is due to the smell of the thiol used as the odorant.
• In the olfactory system, odorant molecules in the mucus bind to G-protein receptors on olfactory cells.
• Odorant receptors bind odorants in the airspace, which are made soluble by the serous secretions from olfactory glands located in the lamina propria of the mucosa.
• Olfactory receptors (ORs), also known as odorant receptors, are chemoreceptors expressed in the cell membranes of olfactory receptor neurons and are responsible for the detection of odorants (for example, compounds that have an odor) which give rise to the sense of smell.
• Among the different types of human skin glands, body odor is primarily the result of the apocrine sweat glands, which secrete the majority of chemical compounds that the skin flora metabolize into odorant substances.
• The blowout involved gas stored under pressure in an underground reservoir; the stored gas included mercaptan (tert-Butylthiol), an odorant added to the odorless natural gas to produce a "rotten egg" smell for safety.
• This chiral lactone is a powerful odorant, which can impart a nutty, caramel, curry, or rancid odor, depending on its concentration and enantiomeric distribution.
• While this theory of odorant recognition has previously been described as the shape theory of olfaction, which primarily considers molecular shape and size, this earlier model is oversimplified, since two odorants may have similar shapes and sizes but are subject to different intermolecular forces and therefore activate different combinations of odorant receptors, allowing them to be distinguished as different smells by the brain.
• This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its protein odorant receptor (found in the nasal epithelium), such as electrostatic and Van der Waals interactions as well as H-bonding, dipole attraction, pi-stacking, metal ion, Cation–pi interaction, and hydrophobic effects, in addition to the molecule's conformation.
• Sustentacular cells of the olfactory epithelium (also called supporting cells or Sertoli cells) have been shown to be involved in the phagocytosis of dead neurons, odorant transformation and xenobiotic metabolism.
• In insects, the olfactory pathway starts at the antennae (though in some insects like Drosophila there are olfactory sensory neurons in other parts of the body) from where the sensory neurons carry the information about the odorant molecules impinging on the antenna to the antennal lobe.
• The development of machine olfaction is complicated by the fact that e-nose devices to date have responded to a limited number of chemicals, whereas odors are produced by unique sets of (potentially numerous) odorant compounds.
• In mice vomeronasal sensory neurons, an odorant receptor coding sequence's exogenous transcription from a V1R promoter can stop endogenous V1R genes from being transcribed.
• On the molecular level, as ORNs depolarize in response to an odorant the G-protein mediated second messenger response activates adenylyl cyclase.
• TMAO decomposes to trimethylamine (TMA), which is the main odorant that is characteristic of degrading seafood.
• has found that people with the intact human odorant receptor OR7D4 are more sensitive to androstenone and androstadienone and thus find them unpleasant (individuals with the semi-functional OR7D4 have two non-synonymous single nucleotide polymorphisms in the OR7D4 pseudogene, resulting in two amino acid substitutions).
• It is contained in human breath and sweat, and it is believed that insect repellent DEET works by blocking the insects' octenol odorant receptors.
• Under an alternative definition, cacosmia is used for an unpleasant perception of an odorant due specifically to nasosinusal or pharyngeal infection.
• Nonsynonymous substitutions in the OR10G4 gene have a significant effect on the perception of the "smoky" odorant guaiacol.
• Tetrahydrothiophene (THT), used as an odorant for natural gas, usually in mixtures containing tert-butylthiol.
