Coniferyl aldehyde
Coniferyl aldehyde is a low molecular weight phenolic compound susceptible to be extracted from cork stoppers into wine. Metabolism. Coniferyl-alcohol dehydrogenase uses coniferyl alcohol and NADP to produce coniferyl aldehyde, NADPH, and H. Coniferyl-aldehyde dehydrogenase uses coniferyl aldehyde, HO, 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.
