Volatile compounds can be responsible for signals that interact with receptor molecules and are amplified by biological signaling chains. As such, they are biologically active compounds. They are often responsible for biological signals that are important for communication within a species or between species. These signaling systems exist in both plants and animals. In animals, signaling is mainly via neurons, which transmit a current to the brain, giving rise to a perception.
