Glossary: sclareol = (13R)-labd-14-ene-8α,13-diol
(13E)-8α-hydroxylabd-13-en-15-yl diphosphate = copal-8-ol diphosphate
Other name(s): SS
Systematic name: (13E)-8α-hydroxylabd-13-en-15-yl-diphosphate-lyase (sclareol forming)
Comments: Isolated from the plant Salvia sclarea (clary sage). Originally thought to be synthesized in one step from geranylgeranyl diphosphate it is now known to require two enzymes, EC 18.104.22.168, copal-8-ol diphosphate synthase and EC 22.214.171.124, sclareol synthase. Sclareol is used in perfumery.
