diferulic

Diferulic refers to a family of hydroxycinnamic acid dimers formed by the oxidative coupling of ferulic acid residues in plant cell walls. These cross-links occur mainly in the walls of grasses and cereals, where ferulic acid esters bridge arabinoxylans and other polysaccharides, contributing to wall structure and rigidity. The dimers are produced during cell-wall maturation through radical coupling reactions mediated by oxidative enzymes such as peroxidases and laccases.

Common isomeric forms include 5–5', 5–8', 8–5', and 8–8' diferulic acids, named for the carbon positions that

Diferulic cross-links increase the recalcitrance of plant cell walls by linking arabinoxylans to each other and

Analytical measurement typically involves alkaline hydrolysis to release diferulic acids, followed by high-performance liquid chromatography or

Biotechnological and breeding approaches aim to modulate diferulic content to improve animal nutrition, processing quality, or
