Compound as reactive (2)
NADPH + sitosterol + H+ + oxygen → 2 H2O + NADP+ + stigmasterol
sitosterol + UDP-α-D-glucose → β-sitosterol 3-O-β-D-glucoside + H+ + UDP
Compound as product (2)
NADP+ + sitosterol ← NADPH + isofucosterol + H+
NADPH + Δ24-25-sitosterol + H+ → NADP+ + sitosterol
Reversible reaction (1)
NAD+ + sitosterol ↔ NADH + 3-oxo-24-ethyl-cholest-5-ene + H+
