Coniferyl aldehyde is an organic compound with the formula HO(CH3O)C6H3CH=CHCHO. It is a derivative of cinnamaldehyde, featuring 4-hydroxy and 3-methoxy substituents. It is a major precursor to lignin.[1][2]

Biosynthetic role

[edit]

In sweetgum (Liquidambar styraciflua), coniferyl aldehyde is a precursor to sinapaldehyde via hydroxylation mediated by coniferyl aldehyde 5-hydroxylase.[3]

Coniferyl aldehyde is reduced to coniferyl alcohol by the action of dehydrogenase enzymes.[2]

It is found in Senra incana (Hibisceae). It is a low molecular weight phenol that is susceptible to extraction from cork stoppers into wine.[4]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
