General description

Sinapyl alcohol, a monolignol, is a primary lignin monomer. It has been evaluated for anti-inflammatory and antinociceptive activities. It participates in the initial stages in the biosynthesis of lignin. Coupling reactions of sinapyl alcohol and sinapyl p-hydroxybenzoate has been reported. Preparation of sinapyl alcohol by selective 1,2-reduction of corresponding cinnamate esters using diisobutylaluminium hydride as reducing agent has been studied.

Application

Sinapyl alcohol may be employed in the preparation of lignin, a highly stable biopolymer.

Green leaf volatiles (GLVs), including six-carbon (C6) aldehydes, alcohols, and esters, are formed when plant tissues are damaged. GLVs play roles in direct plant defense at wound sites, indirect plant defense via the attraction of herbivore predators, and plant-plant communication.

This study describes the substrate recognition profile of UGT72E1, an UDP-glucose:glycosyltransferase of Arabidopsis thaliana that is the third member of a branch of glycosyltransferases, capable of conjugating lignin monomers and related metabolites. The data show that UGT72E1, in contrast to

Most of the known 4-coumarate:coenzyme A ligase (4CL) isoforms lack CoA-ligation activity for sinapic acid. Therefore, there is some doubt as to whether sinapic acid contributes to sinapyl alcohol biosynthesis. In this study, we characterized the enzyme activity of a
