Compound as reactive (2)
campesterol + NADP+ → crinosterol + NADPH + H+
campesterol → campest-4-en-3β-ol
Compound as product (2)
campesterol + NADP+ ← NADPH + H+ + 24-methylenecholesterol
NADPH + 24-methyldesmosterol + H+ → campesterol + NADP+
Reversible reaction (2)
campesterol + NADPH + H+ + oxygen ↔ H2O + (22α)-hydroxy-campesterol + NADP+
2 H+ + 24-methyldesmosterol ↔ campesterol
