Metabolism

Coniferyl-alcohol dehydrogenase uses coniferyl alcohol and NADP⁺ to produce coniferyl aldehyde, NADPH, and H⁺.

Coniferyl-aldehyde dehydrogenase uses coniferyl aldehyde, H₂O, NAD⁺, and NADP⁺ to produce ferulate, NADH, NADPH, and H⁺.

Dihydroflavonol 4-reductase uses sinapaldehyde or coniferyl aldehyde or coumaraldehyde and NADPH to produce sinapyl alcohol or coniferyl alcohol or coumaryl alcohol respectively and NADP⁺.
