In organic chemistry|lang=en terms the difference between lignan and monolignol

is that lignan is (organic chemistry) any of a class of phenylpropanoid (propylbenzene) type of molecules found in essentially all plants, generally dimeric or higher order, and produced by secondary metabolic pathways branching off of aromatic amino acid biosynthesis, in some cases having associated antioxidant or estrogenic (phytoestrogenic) activities; having in common with lignin the phenylpropanoid monomers, where lignin is a random oxidative polymerization of the same while monolignol is (organic chemistry) any of a class of phenolic alcohols, found in plants, that take part in the biosynthesis of lignans and lignin.
