Compound as reactive (2)

NAD(P)+ + 3β-hydroxy-4β-methyl-5α-cholest-7-ene-4α-carboxylate → 4β-methyl-5α-cholest-7-en-3-one + NAD(P)H + CO₂

NAD(P)+ + 3β-hydroxy-4β-methyl-5α-cholest-7-ene-4α-carboxylate → NAD(P)H + 4α-methyl-5α-cholest-7-en-3-one + CO₂

Compound as product (1)

2 H⁺ + 3 NAD(P)H + 3 oxygen + 4,4-dimethyl-5α-cholest-7-en-3β-ol → 3 NAD(P)+ + 4 H₂O + 3β-hydroxy-4β-methyl-5α-cholest-7-ene-4α-carboxylate

Reversible reaction (1)

NAD(P)H + 3β-hydroxy-4β-methyl-5α-cholest-7-ene-4α-carbaldehyde + oxygen ↔ H₂O + NAD(P)+ + 3β-hydroxy-4β-methyl-5α-cholest-7-ene-4α-carboxylate
