hajumolekyyleistä
Hajumolekyylit, often referred to as odorant molecules, are airborne chemical compounds that trigger the sense of smell when they interact with olfactory receptors in the nasal cavity. These molecules possess specific three-dimensional shapes and chemical properties that allow them to bind to corresponding receptors, initiating a cascade of neural signals that are interpreted by the brain as a particular scent. The diversity of smells in the world arises from the vast array of different molecular structures that can act as odorants.
The process begins with the release of volatile compounds from their source, such as food, flowers, or
The human olfactory system can detect a remarkable range of concentrations, and even very low levels of
