Aroma compound - Wikipedia
WEBAn aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
Structural basis of odorant recognition by a human odorant
WEBMar 15, 2023 · 31 Citations. 468 Altmetric. Metrics. Our sense of smell enables us to navigate a vast space of chemically diverse odour molecules. This task is accomplished by the combinatorial activation of...
Understanding the molecular mechanisms of odorant binding and …
WEBDec 7, 2023 · Humans perceive numerous odors from the environment. Olfaction, or the sense of smell, is initiated by the stimulation of odorant receptors (ORs) by odorants 1,2.
The Structural Properties of Odorants Modulate Their Association …
WEBJan 22, 2021 · The binding of known odorant molecules to the human odorant-binding protein (hOBP) was evaluated in silico. Docking experiments elucidate the preferable binding site and binding affinity of odorant molecules to hOBP. The physicochemical properties molecular weight (MW), vapor pressure (Vp), hydrophobicity level (logP), …
Understanding Smell | Ask A Biologist
WEBSep 14, 2017 · Something in the Air. Your sense of smell is called olfaction. Your sense of smell relies on your nose’s recognition of tiny particles in the air called odorants. Odorant particles are released from their source for many different reasons.
Odorant Receptors - The Neurobiology of Olfaction - NCBI Bookshelf
WEBA series of physiological and biochemical experiments performed during the mid-1980s indicated that odorant activation of olfactory sensory neurons was mediated by a G-protein-dependent pathway, which led to activation of adenylyl cyclase, increases in intracellular concentrations of cyclic adenosine monophosphate (cAMP), activation of cyclic nu...
Olfaction: From Odorant Molecules to the Olfactory Cortex
WEBJun 1, 2004 · What is an odor? What is the odor of a flower or that of our favorite food? Several types of volatile odorant molecules detach from a flower or from the food, even though we perceive them as a unique odor. Let’s try to follow which events volatile molecules of diverse molecular structure are causing in the vertebrate olfactory system.
Decomposition of an odorant in olfactory perception and neural
WEBMar 18, 2024 · In the olfactory bulb, where the axons of olfactory sensory neurons converge onto stereotypically positioned glomeruli, different odorants evoke distinct and distributed spatial patterns of...
