[Oxidized NADPH---hemoprotein reductase]
Farnesyl pyrophosphate → (+)-Thujopsene + Pyrophosphate
Farnesyl pyrophosphate → (+)-β-Chamigrene + Pyrophosphate
(S)-2,3-Epoxysqualene → Chair-chair-chair-boat triterpenoid
Squalene → Chair-chair-chair-chair Triterpenoid
Farnesyl pyrophosphate → (+)-α-barbatene + Pyrophosphate
Farnesyl pyrophosphate → Pyrophosphate + γ-bisabolene
Hydrogen Ion + NADPH + Presqualene diphosphate → NADP + Pyrophosphate + Squalene
2 Farnesyl pyrophosphate → Presqualene diphosphate + Pyrophosphate
Oxygen + Squalene + [Reduced NADPH---hemoprotein reductase] → (S)-2,3-Epoxysqualene + Water + [Oxidized NADPH---hemoprotein reductase]
