Animals can easily detect hundreds of thousands of odors in the environment with high
sensitivity and selectivity. With the progress of biological olfactory research, scientists have …

Inspired by the powerful biological olfaction, scientists extracted numerous materials such as
olfactory sensory neuron, olfactory receptor (OR) protein, and odorant binding protein from …

The olfactory system uses hundreds of odorant receptors (ORs), the largest group of the G-
protein-coupled receptor (GPCR) superfamily, to detect a vast array of odorants. Each OR is …

Olfactory receptors (ORs), taste receptors and opsins are well-known for their pivotal roles in
mediating the senses of smell, taste and sight, respectively. However, in the past two …

A new hypothesis for the mechanism of olfaction is presented. It begins with an odorant
molecule binding to an olfactory receptor. This is followed by the quantum biology event of …

Mammalian odorant receptors (ORs) are crucial for detecting a broad spectrum of odorants,
yet their functional expression poses a significant challenge, often requiring Receptor …

Indole is widely present in nature and contributes significantly to the smell of flowers and
animal excretion. However, the odor perception mechanism for indole is unclear, despite …
