CE ÎNSEAMNĂ PINENE ÎN ENGLEZĂ?
pinen
Pinenul este un compus chimic biciclic monoterpenic. Există două izomeri structurali de pinen găsiți în natură: α-pinen și β-pinen. După cum sugerează și numele, ambele forme sunt constituenți importanți ai rășinei de pin; ele se găsesc, de asemenea, în rășinile multor alte conifere, precum și în plantele neconiferice, cum ar fi cremă de mare. Ambii izomeri sunt utilizați de multe insecte în sistemul lor de comunicare chimică.
