CE ÎNSEAMNĂ THC ÎN ENGLEZĂ?
de tetrahidrocanabinol
Tetrahidrocanabinolul (THC), sau mai precis principalul său izomer (-) - trans-Δ9-tetrahidrocanabinol ((6aR, 10aR) -delta-9-tetrahidrocanabinol), este constituentul principal al canabisului. Primul izolat în 1964, în forma sa pură, de către oamenii de știință israelieni Raphael Mechoulam și Yechiel Gaoni de la Institutul de Știință Weizmann, este un solid sticlos de apă rece atunci când devine vâscos și lipicios dacă este încălzit. O formulare farmaceutică a (-) - trans-A9-tetrahidrocanabinolului, cunoscută prin dronabinolul său INN, este disponibilă prin prescripție în S.U.A. și Canada sub numele de Marinol. Un terpenoid aromatic, THC are o solubilitate foarte scăzută în apă, dar solubilitate bună în majoritatea solvenților organici, în special lipide și alcooli. Ca și majoritatea metaboliților secundari farmacologic activi ai plantelor, se presupune că THC în canabis este implicat în autoapărare, poate împotriva erbivorelor. THC posedă, de asemenea, proprietăți de absorbție ridicate UV-B (280-315 nm), care, speculat, ar putea proteja planta de expunerea la radiații UV dăunătoare.
