Many plants are able to create biomolecules with more or less complex processes based on their evolutionary development. They create them with many objectives: dissuade animals that could be threatening, encourage the arrival of insects to be pollinated, resist the attack of fungi in times of great moisture, endure the onslaught of summer heat…

The strategies can become so complex as the interaction of life with the environment. The aromas represent a whole biochemical group that have their high volatility in common. Hence the animal kingdom is able to perceive them so well through the sense of smell. In addition, the small molecular size of the aromas is strategic when metabolizing in third parties, affecting behavior patterns through the nervous system and conditioning or harming other biological groups with their atmospheric action.
