Lignans Biosynthesis - an overview | ScienceDirect Topics
Lignan biosynthesis involves the regio- and stereochemically controlled oxidative coupling of two phenols, e.g. the formation of (+)-pinoresinol from two molecules of coniferylalcohol (Davin et al., 1997).
Distribution, biosynthesis and therapeutic potential of lignans
The biosynthesis of linseed involves four pathways which are (1) the phenylpropanoid pathway (2) stereospecific coupling by dirigent proteins (3) biosynthesis of dibenzylbutane lignans and (4) glycosylation of lignans into SDG.
Lignans Biosynthesis - an overview | ScienceDirect Topics
The biosynthesis of lignans begins with the coupling of two residues of a coniferyl alcohol, this leads to the formation of pinorezinol. This molecule is the main intermediate leading to the formation of different classes of lignans.

Distribution, biosynthesis and therapeutic potential of lignans
Biosynthesis of lignans. Lignans are synthesized by the regional- and stereospecific coupling of biomolecular phenoxy radicals, which is mediated by dirigent proteins (Pickel et al. 2010). They're synthesized from the phenylpropanoid pathway (Fig. 4), with coniferyl alcohol as a precursor. In the presence of dirigent proteins, two molecules of ...
Functions and mechanisms of enzymes assembling lignans and …
2024年6月1日 · Lignans typically consist of a C6–C3–C3–C6 core that originates from two phenylpropanoid units through oxidative coupling. During lignan biosynthesis, peroxidase and oxidase enzymes catalyze the one-electron oxidation of the monolignol precursor to form the corresponding phenoxy radical, thereby promoting the subsequent dimerization steps.
