sinapyl alcohol

Sinapyl alcohol is an organic compound derived from cinnamic acid.

Sinapyl alcohol is a precursor to lignin or lignans.

Chemically, it is the glucoside of sinapyl alcohol.

Hardwood lignin is primarily derived from sinapyl alcohol and coniferyl alcohol.

Together with sinapyl alcohol and coniferyl alcohols, p-coumaric acid is a major component of lignin.

There are three main monolignols: coniferyl alcohol, sinapyl alcohol and paracoumaryl alcohol.

It is the precursor to ferulic acid, coniferyl alcohol, and sinapyl alcohol, all of which are significant building blocks in lignin.

Sinapyl alcohol and paracoumaryl alcohol, the other two lignin monomers, are found in angiosperm plants and grasses.

Further reduction provides monolignols including coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol, which vary only in their degree of methoxylation.

There are three monolignol monomers, methoxylated to various degrees: p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol (Figure 3).

It contains subunits derived from p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol and is unusual among biomolecules in that it is racemic.

The enzyme dihydroflavonol 4-reductase uses sinapaldehyde and NADPH to produce sinapyl alcohol and NADP.

In Arabidopsis thaliana, the enzyme uses sinapaldehyde or coniferyl aldehyde or coumaraldehyde and NADPH to produce sinapyl alcohol or coniferyl alcohol or coumaryl alcohol respectively and NADP.

When other monolignols, such as p-coumaryl alcohol and sinapyl alcohol, are reacted in vitro with oxidative enzymes in the presence of dirigent protein, they produce a heterologous mixture of products indistinguishable from identical experiments in the absence of dirigent protein.
