odorant

An American biologist whose landmark paper published in 1991 described how hundreds of genes code for the odorant sensors located in the olfactory neurons of our noses.

This tissue becomes inflamed, temporarily disrupting the ability of the olfactory neurons to signal the presence of an odorant.

Richard Axel and Linda Buck had just made their fabulous discovery of the olfactory receptors in the rodent nose, which was the key to understanding how odorants give rise to the sense of smell.

Further, Lamarck has short notices of it under "Canang odorant, Uvaria odorata."
